Robert De Niro

Jennifer Lawrence was the woman of the hour at The Weinstein Company's post-SAG Awards party hosted by Fiji Water at Sunset Tower in LA last night. She picked up the award for best actress for her role in Silver Linings Playbook and celebrated with costars Bradley Cooper and Robert De Niro at the bash. Jennifer also posed alongside fellow nominee Naomi Watts, who presented at the show with Liev Schreiber. Jennifer's big night wasn't dampened by her recent walking-pneumonia diagnosis, which she's battling with "a lot of medication," or by the fact that she almost ripped her dress while heading to the stage to accept her statue.

Plenty of other stars kicked back after the SAGs at another soiree held at the Chateau Marmont. Ben Affleck and his wife, Jennifer Garner, toasted his Argo win while the cast of Les Misérables met up with winner Anne Hathaway — make sure to check out the full list of SAG Award winners!

Bradley Cooper enjoyed the last days of his reign as People's Sexiest Man Alive last night on the red carpet at the NYC premiere of Silver Linings Playbook. The magazine announces their 2012 pick tomorrow! Yesterday, Bradley was in the company of costars Robert De Niro, Jacki Weaver, Chris Tucker, and Julia Stiles. We spoke with Bradley about the joys of shooting the picture in his hometown, Philadelphia. He said, "This was a good chance to shoot Philly for Philly . . . the neighborhood, the people. It felt very close to home. My uncles were there. My uncle read [Robert De Niro's] lines for [Robert] to get the accent. Jacki Weaver hung out with my mom. It was kind of a family affair."

Absent from the film's Big Apple premiere was Bradley's leading lady Jennifer Lawrence. Jennifer was able to promote their film over the weekend, though. Jennifer Lawrence showed off her dark hair, and an all-black outfit, for a special screening on Sunday. She was nonetheless present in the minds of her costars last night. Costars like Chris called Jennifer's performance in Silver Linings Playbook "great" and "fantastic" — stay tuned for more on Jennifer and Bradley in this afternoon's PopSugar Rush.

Last night's Hollywood Film Awards brought plenty of stars to the Beverly Hilton Hotel. Few attendees went home empty-handed — Bradley Cooper won the Hollywood Actor Award, Marion Cotillard the Hollywood Actress Award, and Amy Adams the Hollywood Supporting Actress Award. Ben Affleck also added to his statue collection, since he and the cast of his third directorial project, Argo, won the Hollywood Ensemble Acting Award. He accepted the prize in the company of Bryan Cranston, John Goodman, and Alan Arkin. Judd Apatow, meanwhile, accepted his Hollywood Comedy Award.

We caught up with Bradley on the red carpet before the show began. He spoke about working with Jennifer Lawrence in their forthcoming Silver Linings Playbook, revealing that on their very first day on set, the ice was broken right away since they had to practice a dance scene. Many of the attendees' minds were on the third presidential debate, however. Bradley told us his advice to young people this election season is to vote, while Kerry Washington showed off her Barack Obama 2012 iPhone case.

Ben Affleck and Marion Cotillard were among those who stepped out for last night's Hollywood Film Awards in LA. Marion hit the red carpet in a strapless gown from Dior, while Amy Adams also attended in a long Oscar de la Renta number. A Prabal Gurung-clad Amanda Seyfried, Kerry Washington, and Irish actress Kelly Reilly rounded out the list of ladies heading into the show. Bradley Cooper, Robert De Niro, and Bryan Cranston were also on hand. The Hollywood Film Awards are generally regarded as the first of award season, which gets into full swing in early 2013. Argo was honored for the acting skills of their cast, while Robert and Bradley picked up statues for their forthcoming Silver Linings Playbook. Richard Gere received a lifetime achievement award, while Amy and Marion got individual acting honors.

Jennifer Lawrence, in a dramatic Dior Couture gown, and Bradley Cooper teamed up in Toronto to show off Silver Linings Playbook at the city's film festival tonight. It was Bradley's second red carpet at the event after premiering The Place Beyond the Pines with Ryan Gosling yesterday. Jennifer made an appearance at that screening as well to show her support for her costar. She's sporting darker hair for her role as Katniss in the second installment of The Hunger Games, which she'll start filming next week. Sam Claflin was recently added to the cast, as was Jeffrey Wright.

The stars came out to celebrate during the Cannes Film Festival in France yesterday. Gerard Butler, Adrien Brody, and Karolina Kurková were just a few of the guests at IWC and Finch's Quarterly Review filmmakers dinner, which was held at the Hotel Du Cap. Model Karolina — who tweeted of the event, "What a night!" — and Petra Nemcová got together for a playful photo, while Gerard met up with pals Robert De Niro, Ewan McGregor, and Adrien. Petra's boyfriend, Sean Penn, wasn't by her side for this bash, though they were together for the Haiti: Carnival in Cannes event. There's been so much excitement at Cannes so far, but there's even more to come, as both Brad Pitt and Kristen Stewart are still expected to hit the red carpet this week.

Chanel played host last night at its annual Tribeca Film Festival Artists Dinner held inside NYC's Odeon restaurant. Many of the ladies donned Chanel for the occasion, including Alexa Chung and Leelee Sobieski — who's your pick for best dressed at Chanel's dinner? Naomi Watts went with a simple LBD to pose alongside Liev Schreiber, while Liv Tyler posed solo. Many of the film festival's jurors turned out, like Kellan Lutz and Camilla Bella, and founders Robert De Niro and Jane Rosenthal swung by as well. The cinema fun wraps up Sunday, April 29. Make sure to check out all the Tribeca Film Festival pictures, and click through to see what Leelee, Julia Restoin-Roitfeld, model Lily Donaldson, and more wore to Chanel's soiree.
