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 rolled up his jeans to hit the sandbox with Billie in Beverly Hills on Sunday. It was the second park day in a row for the 1-year-old after she had a play date with mom Rebecca Gayheart on Saturday. Rebecca, who is pregnant with the couple's second child, was later spotted grabbing lunch at Joan's on Third. Eric seems to be all about spending quality time with his daughter after returning home from a stint in rehab, and the duo had a similarly smiley outing earlier this month. Eric is not only back to his family, but he's also getting to work on Grey's Anatomy. A new promo for Grey's Anatomy was released last week, and though the eighth season doesn't air for about a month, the teaser does reveal a few spoilers. Eric's costar Kevin McKidd also shared details about the show at Disney's D23 Expo this weekend, saying things are going to be rocky for his character Owen and onscreen wife Cristina.

Eric Dane had Billie in his arms and a smile on his face at Coldwater Park in Beverly Hills yesterday. He spent the sweet day with his daughter now that he's returned home from a stint in rehab. Eric voluntarily checked himself into a treatment facility earlier this Summer in order to overcome a battle with a pain medication that was prescribed to him following a sports injury. The actor completed his 30-day program and returned to work on the eighth season of Grey's Anatomy late last month. Eric looked happy and healthy during his latest outing and he has even more reason to celebrate since his wife, Rebecca Gayheart, who rang in her 40th birthday last week, is reportedly pregnant with the couple's second child.

Some of Hollywood's biggest stars stepped out with their families to celebrate Father's Day over the weekend. Tom Cruise went sailing with Suri and Katie Holmes off the coast of Miami, while Tom Brady relaxed close to home in LA with wife Gisele Bundchen and sons Jack and Benjamin. Cash Warren had his last holiday as a dad of one at a California park with Jessica Alba and Honor, and Hugh Jackman played photographer to capture daughter Ava splashing around in NYC. There was plenty of fun to go around, so click through to what they were all up to!

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.
