A few of the most fashionable celebrities in Hollywood turned out for Chanel's pre-Oscars dinner in LA last night. Best actress nominee Jessica Chastain and Kate Bosworth wore Chanel dresses for the event, where they rubbed elbows with Rosie Huntington-Whiteley, Ginnifer Goodwin, January Jones, and Rachel Zoe.

Jessica walked the red carpet solo, but she raised plenty of eyebrows the previous night when she left the Women in Film pre-Oscars bash with boyfriend Gian Luca Passi de Preposulo. She has been notoriously tight-lipped about her romantic life, but it was revealed that Jessica Chastain's boyfriend has connections to the fashion industry: he's an executive at Moncler. However, Jessica will be taking her grandmother — not boyfriend Gian — to the Oscars, where she is up for the best actress prize. Don't forget to tune in to our LIVE Oscars red carpet coverage and viewing party starting tonight at 5:30 p.m. EST/2:30 p.m. PST.

Adriana Lima and Karolina Kurkova donned sexy black dresses to attend watch brand IWC Schaffhausen's party at Salon International de la Haute Horlogerie last night in Geneva, Switzerland. The models were joined by Ewan McGregor and Kevin Spacey as well as Rebecca Gayheart and Eric Dane for the event. Karolina also donned a bright red ensemble, while Adriana emerged in a black-and-white dress to pose for the festivities. Adriana made the trip overseas after taking care of modeling duties for Victoria's Secret. Adriana and Erin Heatherton launched VS's new fitness line together at the brand's Herald Square NYC store last week. Ewan, meanwhile, traveled to Switzerland following his appearance at the Golden Globes earlier this month, when he was nominated for Salmon Fishing in the Yemen.

A whole host of lovely ladies stepped out in Culver City, CA, on Saturday for the first-ever Baby2Baby Gala held at the Book Bindery. The event honored the organization's board member and ambassador, Jessica Alba, who wore Valentino for the special night and was presented her award by Mindy Kaling. Jessica tweeted to Mindy, "Thank you so much for presenting my award last night, it was truly an honor and Cash Warren is still blushing!" Board member Nicole Richie attended in a gown by Lorena Sarbu while Modern Family's Julie Bowen wore Naeem Khan. Also on hand were Busy Philipps, Rachel Zoe, Ali Larter, and Rebecca Gayheart. A few of their men came along to show their support as well, with Rachel's husband, Rodger Berman, stepping out and Rebecca's man, Eric Dane, also making an appearance.

Eric Dane and Rebecca Gayheart made a quick trip north to San Francisco with their daughter, Billie, on Saturday. The family of three were in town to host the grand opening of Kiehl's new skin-care store on Fillmore Street, and Eric helped cut the ribbon to kick off the festivities. The event also honored Kiehl's homeless prenatal program, with the company donating $10,000 to the cause in honor of Eric. Little Billie got plenty of attention during the city outing, which fell ahead of Father's Day. Eric was just one of many hot Hollywood dads to enjoy a family-filled Sunday.

It was a star-studded afternoon at Coldwater Park in LA on Saturday. Jessica Alba wore a TEXTILE Elizabeth and James cardigan to bring her daughter Honor to play on the swings and hang in the grass as Rebecca Gayheart and Eric Dane entertained their little one, Billie. The Hollywood parents chatted with each other while tending to their girls. Eric was able to enjoy the sunny weather with his family now that Grey's Anatomy wrapped with an exciting season finale last week. Eric and Rebecca's Summer plans include moving into a new home, and he hopes to teach little Billie how to swim. Jessica, meanwhile, made the casual outing before heading to a friend's wedding that evening with Cash Warren, and the festivities were intense enough that Jessica tweeted that a p.m. nap was in order yesterday.

Rebecca Gayheart and her baby girl Billie stopped by a friend's house in LA yesterday while dad Eric Dane picked up a new pair of jeans in West Hollywood. The mother-daughter duo has been all about their day dates lately, and they recently had an exciting milestone to celebrate — Billie turned one last week! Eric conveniently had a break from filming Grey's Anatomy to enjoy the birthday, though he should be getting back to work soon as they wrap up their hiatus. The series will return on March 31 with a fun musical episode, though Derek and Meredith's struggle with infertility continues to be a serious storyline. Ellen Pompeo recently talked to LilSugar about her character's onscreen issues, and she also shared her real-life thoughts on "having it all."

Rebecca Gayheart stepped out in LA yesterday with her daughter Billie and a nanny. The trio was off to visit a friend's house, with baby Billie wearing little pink knit booties for the occasion. Billie and Rebecca have been able to enjoy the great Southern California weather this Winter, hitting the park for playdates and enjoying walks out in the sun. Rebecca and her husband Eric Dane have been able to enjoy some adults-only time, however, stepping out for a black tie date night with their famous friends. He's been busy in recent weeks working on Grey's Anatomy, and he'll apparently stay that way until next year as the series was recently renewed. He's among the many stars of the program who are parents to young children — test your knowledge of the cast's kids by taking Lil's quiz! The baby boom is transitioning over to the small screen as well, since one of the characters on the show is pregnant now too.
