Jennifer Aniston

This Summer, some of the most well-known women in Hollywood will be lighting up the big screen as superheroes, cops, magicians, '90s teens, and more. While some actresses are returning to popular roles for sequels, others will be treading in new territory — like Emma Watson, who's playing a shallow socialite in Sofia Coppola's latest film. We've already shown you the boys of Summer, so now take a look at the leading ladies of Summer!

It was an exciting week for stars between film festivals, family, and bikini fun. Miranda Kerr got sexy in a swimsuit for a hot Miami photo shoot, while Leonardo DiCaprio linked up with his The Great Gatsby costars for a glamorous photocall in Cannes. Jennifer Aniston hit the pavement in NYC for a shopping trip with fiancé Justin Theroux, and Jennifer Lopez turned up the heat during her performance on the American Idol finale.

Jennifer Aniston and Justin Theroux shopped for furniture on NYC's Upper East Side today. The retail stop comes after a busy Big Apple weekend for the pair. Yesterday, Jennifer and Justin had brunch at the famed Fred's restaurant in Barneys department store, and on Saturday night, the couple indulged in a sushi dinner at Nobu with friends.

While Jen has been able to spend time with Justin on the East Coast, she's also had her fair share of solo outings. On Friday, Jen took in Bette Midler's Broadway show I'll Eat You Last with a group of pals followed by dinner at Trattoria Dell'Arte restaurant.

Jennifer Aniston and Justin Theroux went shopping together at Barneys in NYC yesterday. On Saturday night, before their shopping trip, the couple dropped by Nobu, where Jennifer donned her new hipster glasses, and Justin kept warm in a green jacket. Jennifer is in the Big Apple to tend to promotional duties for her new Living Proof web series, Good Hair Day. While doing press for the new series, Jennifer's longtime friend and stylist Chris McMillan caused a bit of controversy when he revealed that he was stoned when he created the "Rachel" cut back in 1994. However, he noted that he has been 14 years sober so he "feels safe" admitting to his secret now.

Jennifer and Justin have been reportedly busy planning their upcoming wedding. The two were allegedly supposed to get hitched back in the Spring, but the date got pushed back. Aside from her nuptials, Jennifer has another big goal on the horizon — she wants to direct. She said in an interview that she hopes to direct a full-length feature within the next five years.

Jennifer Aniston went geek chic when she checked out Bette Midler's new Broadway play during a night out with friends in NYC last night. She wore retro glasses as she dropped by a performance of I'll Eat You Last with a group of pals before heading over to Trattoria Dell'Arte to grab dinner. The show is based on the life of Hollywood agent Sue Mengers, who was very close to Jennifer before her death in 2011. A piece in the December 2011 edition of The New York Times Magazine contained the out-there story that Mengers consoled Jen after her split from Brad Pitt and even advised asking Brad for sperm.

Jennifer has been spending the past few days in the Big Apple as she does press for her new Living Proof web series, Good Hair Day, which she premiered on Wednesday. POPSUGAR Beauty interviewed Jen about the new series and she spilled that she thinks Kate Moss and Gisele Bündchen have the best hair among female stars.

It was a busy week for stars, between red carpet affairs and work on the set. Robert Pattinson made a secret trip to NYC to join his girlfriend, Kristen Stewart, while Beyoncé Knowles took over the Met Gala stairs in the Big Apple. Anne Hathaway showed off her platinum-blond hair at an artists' dinner with Sarah Jessica Parker, and Jennifer Aniston had a laugh with her hairstylist, Chris McMillan, while promoting her new web series for Living Proof in NYC.

Jennifer Aniston went casual in cargos, flip-flops, and her Tom Ford bag to shop Madison Avenue in NYC yesterday. She's on the East Coast promoting her new Living Proof web series, Good Hair Day, and attended a launch event for the show Wednesday. Jennifer was joined by her hairstylist Chris McMillan for the press day, during which she talked about learning "what not to do" with her hair after cutting it off in her teens. Jennifer also revealed that she loves Kate Moss and Gisele Bündchen's looks, though she might be taking on a different style soon — Chris shared that Jennifer "wants to do a drastic look for" an upcoming role. He's not the only person on Jennifer's team who's talking about her lately, since her yoga teacher Mandy Ingber recently told us that Jennifer is an "amazing, positive force."

Nicole Kidman, Carey Mulligan, and Julianne Moore are the latest in a long list of fashion darlings and actresses to take Raf Simons from the runway to the red carpet. Ever since Belgian designer Simons, formerly of Jil Sander, took the reins at the legendary label, he's presented five exquisite collections. Naturally, stars like Cotillard (the face of Lady Dior) and Jennifer Lawrence (the face of Miss Dior handbags) have flocked to his jaw-dropping gowns, and we can totally see why. Simons is breathing new life into the design house by taking iconic past-collection references (think New Look from the 1940s) and updating them with a modern twist. Step inside to see all the stars who have donned Simons's designs for Dior now.
