Luca Comrie

Hilary Duff escaped to Mexico with her family over the weekend to celebrate Mother's Day. She had husband Mike Comrie, son Luca, and sister Haylie along for the celebratory trip, which she recognized on Twitter, writing, "Feel so very lucky to be a mother today! And everyday! Happy Mother's Day to all the mothers out there, it can be a hard job but the best! Good work!" Hilary also shared her thoughts on motherhood with People recently, adding that, "I think asking for help on a tired day isn't a sign of weakness. A lot of changes have come into your life quickly and it's important to take time for yourself!"

Hilary wore a bikini during the sunny days, which included hanging out poolside, hitting the beach, and kicking a ball around the grass. Hilary is just one of the many famous moms who celebrated Mother's Day in a special way including Jessica Alba, who went out to brunch with her family of four.

For a long time running, it seemed People had a monopoly on introductory celebaby photos. Nicole Richie, Christina Aguilera, Jennifer Lopez, and the Jolie-Pitts all turned to the well-established magazine to show off their newest family members. However, today, many celebs are turning to competitors who are doling out generous offerings to new parents. Others are releasing their own photos — either on their own or through photo agencies — to bypass the whole magazine scenario. See how your favorite Tinseltown parents — Malin Akerman being the most recent — debuted their little ones, and tell us how you think the newest Hollywood babies will be introduced to us!

Hilary Duff carried her son, Luca Comrie, to Babies First Class in LA yesterday. The active mom is back to running errands with Luca after traveling to Indio, CA, over the weekend with her husband, Mike Comrie, and older sister, Haylie Duff, for Coachella.

Fresh off her festival getaway, Hilary has jumped onto promotional duties for the latest and final installment of her Elixir trilogy, True. On Tuesday, she signed hardcover copies of her fictional love story, which was officially released the same day, at a local book shop in La Verne, CA. The multitalented star took to Twitter to share her gratitude: "Great night...Thank you to all my loyal and devoted fans. You guys mean so much to me!" While Hilary soaks in the success of her trilogy's conclusion, she also has a small-screen moment to look forward to. Hilary will guest-star as Ashton Kutcher's onscreen girlfriend on the season finale of Two and a Half Men, which airs May 9.

Hilary Duff visited a Beverly Hills park with her son, Luca, yesterday. Although her husband, Mike Comrie, a former professional hockey player, was absent for the outing, Luca showed his father's influence as he wielded a mini hockey stick for the playdate. Hilary has been spending lots of quality time with her little man lately. Last week, the pair enjoyed a mother-son shopping outing.

Hilary also found time to take on a new small-screen project. Hilary will make a cameo on the season finale of Two and a Half Men, which airs May 9 on CBS. She will be romancing Ashton Kutcher as his love interest in the episode. Hilary took to Twitter yesterday to give more insight into her upcoming guest appearance on the show, saying, "So excited to be joining the cast of Two and a Half Men this week! I get to play a crazy, drunk girl, fun!"

Hilary Duff carried Luca, who rested his head on his mom's shoulder, in her arms as she ran errands around LA yesterday. She's been focusing much of her attention on her little man recently, especially since his exciting milestone. Luca turned 1 last week, and he celebrated by attending a Babies First Class in LA with Hilary. The proud mom was also sure to have a standout cake, which seemed to be a highlight of the festivities. Hilary shared a picture of the robot confection on her Twitter account, saying, "Thank you Duff's cake mix for the coolest 1 year old's robot birthday cake ever! It was a big hit!"

Hilary Duff took her son, Luca Comrie — who turned 1 on Wednesday — to Babies First Class in LA to celebrate his birthday yesterday. The mother-son team are regulars at the interactive mommy-and-me class, having attended multiple times in recent months. Hilary wore a plaid button-down and black shades for the outing, while Luca sucked on a blue pacifier.

Before heading to class, Hilary tweeted a sweet picture of her birthday boy getting the party started with bubbles and a cute dog. She also took to social media on Sunday to share her recent ink job — a small red heart on the outside of her wrist — adding to the long list of celebrities sporting tattoos.

Hilary Duff took her 11-month-old son, Luca Comrie, to a Babies First Class in LA on Wednesday. She wore a loose tie-dye maxi dress, and he sported a "Hello, Ladies" shirt for the interactive mommy-and-me class, which the two have been regularly attending. While Hilary has been clocking in mom duty, she and husband Mike Comrie still find time to sneak away for couple's outings. They attended a Laker game last month and, more recently, the PGA Tour Wives Association 25th Anniversary event in Santa Monica, CA, on Monday. At the golf celebration, Hilary revealed that she's lost 30 pounds since giving birth to Luca in 2012. She credits the weight loss to a combination of circuit training and sculpting Pilates sessions.

Hilary Duff brought little Luca Comrie over to a friend's house for a playdate in Beverly Hills yesterday. The mother-of-one balanced a stylish Céline bag and her baby boy Luca in her arms as she crossed a grassy lawn in a pair of Rag and Bone booties. While those shoes are getting put to good use, some of Hilary's other pairs are being put towards a good cause. Several pairs of Hilary's autographed heels were put up for auction on Ebay recently, and she promoted the listings on Twitter with the hashtag #KickUpYourHeels. Money raised from the fundraiser will help support children's workshops and programs at the Lancaster Opera House Theatre in New York. Other celebrities getting on board include Kelly Clarkson, Brittany Snow, and Ashlee and Jessica Simpson.

Hilary Duff planted a big kiss on her little boy Luca Comrie's cheek on Sunday as she carried him into a Bristol Farms grocery store in LA. The affectionate mom and her hockey-player husband, Mike Comrie, stopped in to go shopping before celebrating their third holiday as a married couple and their first with baby Luca. Hilary paired a brown leather jacket with black booties and a high bun, while a giggling Luca sported stripes and a pair of baby New Balance shoes.

Hilary and Mike may be done having kids, according to a recent statement the mother of one made about their "perfect" little guy, but she still had plenty of holiday love to share. Hilary tweeted, "Happy Christmas Eve! Sending love and merry thoughts to everyone today! Big hugs and kisses!"
