Celebrity Pregnancies

Kate Middleton attended a friend's wedding in a familiar Topshop polka-dot dress on May 11. She was first spotted wearing the black and white look on her Warner Bros. studio tour back in April. This time, it was the perfect outfit for the Spring nuptials of Kate and Prince William's friends William van Cutsem and Rosie Keene, who tied the knot in Ewelme, England. William served as an usher at the ceremony while Kate's sister Pippa and brother James were also in attendance.

The wedding took place while Prince Harry was on his US tour, but now the young royal is back by his brother's side. The two made an official visit to Tidworth, England, yesterday to open four new Help For Heroes recovery centers, which serve wounded service personnel. Kate skipped this event, but that doesn't mean that she hasn't been keeping busy over the past week. Kate has reportedly been taking cooking classes with her new housekeeper, Antonella Fresolone, as she preps for the arrival of her first child. Kate's brother-in-law, Mike Tindall, says Kate is a natural mother, though she'll have plenty of help once the royal baby arrives.

Work it, mamas-to-be! For expectant mamas heading into the Summer season, swimwear selection is always top of mind. Fifty percent of POPSUGAR Moms readers showed off their burgeoning bellies in a bikini while pregnant — and they're not alone. Take a look at some of our favorite expectant celebs who also sported two-piece bathing suits while playing in the sun.

Kate Middleton wore sneakers and jeans to brave the London rain for a shopping trip on Tuesday. She carried her own bags as she made her way to a car after a visit to a home store. Perhaps pregnant Kate was shopping for her new home, Apartment 1A at Kensington Palace, where she and Prince William will move into this Fall. Will and Kate will not go at it alone since they recently hired Antonella Fresolone, a former housekeeper for Queen Elizabeth II, to help them with running their new household.

Kate joined Prince William at a wedding on Saturday to watch pals William van Cutsem and Rosie Ruck Keene tie the knot in a small town in South Oxfordshire. Kate reportedly recycled her polka-dot Topshop dress, which she wore to a Warner Bros. Studios tour last month, to wear to the wedding.

Kim Kardashian donned a white dress with an attached cape to film a scene with mom Kris Jenner for her reality show Keeping Up With the Kardashians at Stanley's Restaurant in LA yesterday. Kim may have been channeling another star through her fashion choice — her outfit was reminiscent of Gwyneth Paltrow's white Tom Ford caped dress from the 2012 Oscars.

Kim, who is due in July, is preparing for a big celebration soon. Her baby shower will reportedly be held on June 2, and special invitations were already sent out for the baby-themed bash. In typical Kardashian fashion, the invites were printed on not your regular shower stationery but rather came in the form of music boxes with a wind-up ballerina that played a special tune when opened. There was no mention of a baby registry, but there were reports last month that Kim and Kanye would not accept baby gifts and instead would be requesting guests to make a donation to Chicago's Lurie Children's Hospital.

As the leading lady of a family known for broadcasting their lives on television, Kim Kardashian has always felt right at home in the spotlight, and her pregnancy's been no exception! For the past several months, Kim's been strutting her stuff across the globe, and making headlines by dressing her bump in seriously high fashion.

Now that she's into her third trimester, take a look at some of the starlet's best maternity style moments. Lights, camera, Kim!

A very pregnant Penélope Cruz was all smiles when she visited her sister, Monica Cruz, at a hospital in Madrid after Monica gave birth to a baby girl yesterday. Penélope was joined by her husband, Javier Bardem, and brother, Eduardo Cruz, as they all piled into a taxi to leave the hospital. Eduardo made a reference to the good news when he posted a photo on his Twitter account that read "Viva La Vida" yesterday.

Monica made headlines back in January when she announced that she had gotten pregnant through an anonymous sperm donor and was planning on raising her baby as a single mother. She announced the news in a blog post for El País, saying, "I'm going to be a mom! I have achieved the dream of my lifetime." Shortly after Monica's news, Penélope and Javier confirmed that they were expecting their second child in February.

Halle Berry teamed up with Modern Family star Julie Bowen to kick off the 20th annual EIF Revlon Run/Walk For Women in LA today. The event raises money for research, treatment, and support of medically underserved women with cancer. She has been a supporter of the beauty brand and its various charities since 1996, when she first signed on as a beauty ambassador. Halle dropped by the charity walk while on a break from filming her upcoming movie, X-Men: Days of Future Past, alongside Hugh Jackman and Jennifer Lawrence. Aside from working, Halle has been keeping active during her second pregnancy and was even spotted wearing gym clothes yesterday leading up to the Revlon event. She isn't the only star who is supporting Revlon's race — Emma Stone and Olivia Wilde hosted the Revlon Run/Walk in NYC last weekend.

Kim Kardashian and her boyfriend, Kanye West, had a busy day today in LA as they reportedly went housing hunting before grabbing lunch together at 9021PHO restaurant in Beverly Hills, CA. On their way into the restaurant, Kanye had a clumsy moment when he hit his head on a street sign and hobbled into Kim's arms. The pregnant reality star consoled her boyfriend as she led the way into the restaurant through the swarming paparazzi.

Kim and Kanye have been inseparable all week and kicked off their couple outings on Sunday over dinner with Anna Wintour, ahead of Monday night's Met Gala. Kim made her first appearance at the fashion event while on Kanye's arm and was serenaded by her boyfriend during his evening performance. Kanye added a line to his song directed at Kim, singing, "You're so awesome," apparently coming to her defense against all her wardrobe critics. The affectionate couple is expected to welcome their baby girl sometime in July.

Both Kim and Kanye are also up for this year's POPSUGAR 100. Vote in our POPSUGAR 100 bracket to pick your favorite star, and enter for a chance to win a Victoria Beckham bag!

Pregnancy at 46 certainly isn't slowing down Halle Berry! Halle put her growing baby bump on display in a tight workout outfit today while running errands in LA. Following her morning workout, Halle was later joined by her daughter, Nahla Aubry. The actress is expecting her second child, her first with fiancé Olivier Martinez, and announced her pregnancy last month while promoting her thriller The Call.

Halle is also working through her pregnancy, since she is currently reprising her role as Storm for X-Men: Days of Future Past. The upcoming movie centers around time travel and alternate dimensions, which is fitting since director Bryan Singer is bringing together the casts from the two originals, X-Men: The Last Stand, and X-Men: First Class. In turn, Halle will share the big screen with former costars Hugh Jackman, Ian McKellen, and Patrick Stewart as well as Michael Fassbender and Jennifer Lawrence. The third installation is due out in Summer 2014, well after Halle's due date.
