Jennifer Aniston posed in a sexy lace top and vest at the premiere of Lifetime's Five in NYC tonight. She directed one of the five short films, which highlight how friends and families deal with breast cancer, and promoted the project earlier today with an appearance on Good Morning America. Jennifer had her man, Justin Theroux, for support at this evening's event, though he waited inside with pal Terry Richardson and joked that no one cares about him while Jennifer worked the press line. Jennifer shared that her favorite thing about being in the Big Apple is the people as she headed into the screening. Also on hand for the special evening were Demi Moore and Alicia Keys, who each contributed their own shorts for the small screen.

Nicole Richie rocked a bikini in Cabo San Lucas on Friday. She was in a strapless black two-piece to lounge by her hotel pool with a similarly swimsuit-clad Samantha Ronson. The girls also showed some skin Saturday during a jaunt to the beach. They're south of the border, hanging out with other pals like Jessica Simpson and Ashlee Simpson. Any rumors that Nicole and her Fashion Star cohost Jessica are feuding were put to rest when the girls met up for lunch yesterday. The fun vacation comes just days after Nicole Richie turned 30. We celebrated by looking back at some of her sweetest moments with pals, and it seems those real-life BFFs whisked her away for a couple days of fun in the sun. On the actual day, last Wednesday, Jessica tweeted to Nicole, "Happy birthday Nicole Richie! Today don't feel guilty about mixing your pressed green juice with vodka. Huge hug and boobie bump!"

Ryan Gosling took a break from filming and hanging out with his rumored girlfriend Eva Mendes in order to take a meeting at LA's Montage hotel today. He's coming off the critically acclaimed release of Drive and has started filming a new movie, The Gangster Squad. Ryan reunites with his Crazy, Stupid, Love costar Emma Stone on the period piece, and they've already rekindled their onscreen romance with a sweet kissing scene for the cameras. Away from the magic and lights of the movies, Ryan, one of Hollywood's most eligible bachelors, has been spending time with another leading lady. Eva Mendes and Ryan took a romantic hike around the Griffith Park Observatory last week following their loved-up trip to Disneyland.

Jennifer Aniston wore a casual tank and sexy black boots on her way into the Good Morning America studios in NYC today. Last time Jen dropped by the early show earlier this Summer, she confessed, "she's extremely lucky and happy" with her personal life. Now, she's talking about her latest directing project, Five. The movie, which is actually five short films about friends and families dealing with breast cancer, gave Jennifer the chance to work alongside Demi Moore and Alicia Keys, who lensed their own segments. Jennifer, Demi, and Alicia share the October cover of Glamour magazine and Jen talked about the importance of this film and their goals as directors. She said, "We wanted stories that were informative without being heavy handed. Oh, and they needed to be brilliantly written. Other than that, our goals were small." Jen and the ladies will meet up again this evening when they premiere the finished product in the Big Apple, and hopefully she and boyfriend Justin Theroux make their red carpet debut!

Rihanna popped up in Ireland today to shoot a new video for her single "We Found Love." She's fresh off a stint in Brazil performing at the Rock in Rio event. Katy Perry, one of Rih's best buds, was also in the city to perform at the weekend-long festival. There was enough downtime that Rihanna could throw on a bikini to chill at the beach with friends between rehearsals and her gig. Amid her hectic schedule of jet-setting, Rihanna also managed to film a cameo for Extreme Makeover: Home Edition. Her episode, the two-hour season premiere, aired last night and also featured special guest First Lady Michelle Obama.
