Leonardo DiCaprio and a Viktor and Rolf-wearing Jennifer Lawrence hung out with Jay-Z at The Great Gatsby's premiere afterparty at The Plaza Hotel in NYC last night. While Jay, Leo, and the rest of the cast walked the red carpet at the Great Gatsby premiere, they got a chance to catch up and mingle at the glamorous bash following the screening. Leo's costars Tobey Maguire, Joel Edgerton, and Isla Fisher attended the postcarpet fete, with Isla staying close to husband Sacha Baron Cohen. The afterparty wraps up a busy week of promotions for the Great Gatsby cast. They have been doing press ahead of the project's May 10 release on Good Morning America and they also attended Prada's glamorous cocktail party for the film on Tuesday. Before the parties and TV appearances, the cast joined up for a press conference in NYC on Sunday — read the five things we learned from The Great Gatsby's revealing press conference.

Anne Hathaway shared laughs and drinks with her Les Misérables costars at a special pre-Oscars bash in LA last night. She donned a Theyskens' Theory minidress as she celebrated with a Dior-wearing Amanda Seyfried, Eddie Redmayne, and Isla Fisher, who attended the shindig with her husband, Sacha Baron Cohen. The Les Misérables fete supported the Los Angeles Fund For Public Education, and drew other celebrities like Adrien Brody and Judy Greer. The celebration wasn't to be confused with the separate Vanity Fair party for Silver Linings Playbook, which also benefited education in LA and was held on the same night.

The pre-Oscars parties are just getting started, and the casts of both films will have plenty of chances to celebrate before Oscar night on Sunday, Feb. 24. Don't forget to fill out our Oscar ballot for a chance to win $1,000 and an iPad.

Golden Globes winners Anne Hathaway and Hugh Jackman celebrated their wins with their fellow award recipients and Hollywood friends when they attended the NBC Golden Globes afterparty last night. Hugh posed with director Tom Hooper while Anne was joined by Les Misérables costars Eddie Redmayne, Amanda Seyfried, and Sacha Baron Cohen on the red carpet. Sacha caused quite the stir at the Globes when he presented and proceeded to roast his fellow costars, including poking fun of Anne's now-infamous up-skirt incident at the film's premiere back in December. However, it looks like Anne wasn't offended by Sacha's ribbing as she happily smiled with him for photos. Jessica Chastain also attended the event and proudly showed off her award while grinning for the photographers. Olympic gold medalists Gabby Douglas, Aly Raisman, and Missy Franklin dropped by the event, along with Smash star Megan Hilty.

Anne Hathaway made a dramatic entrance to the NYC premiere of Les Misérables last night. She wore a striking black Tom Ford gown and bold red lip after donning a floral number for a stop by The Late Show earlier today. Her leading lady Amanda Seyfriend chose a similarly bold look in Alexander McQueen. As they walked into the Zeigfeld Theater, Anne joked about the length of Amanda's train. Anne picked up the back of Amanda's dress and said, "Can I be your bridesmaid?"

Anne and her costars, including Hugh Jackman and Russell Crowe, have been busy promoting the film, which hits theaters on Christmas Day, and attended the big London premiere last week following a trip to Japan. Sacha Baron Cohen and his wife, Isla Fisher, stepped out for that event, as did Eddie Redmayne and Russell.

The Les Misérables fun continued following the world premiere in London's Leicester Square with an afterparty last night. Anne Hathaway changed out of her white Givenchy gown and into a strapless Altuzarra number while Amanda Seyfried swapped her ruffled dress for pants and a jacket. Hugh Jackman, Eddie Redmayne, Sacha Baron Cohen, and Isla Fisher all made their way from the red carpet to the bash, where Goldie Hawn popped up to celebrate. The film's press tour will continue with a big premiere in NYC on Monday, just ahead of the Christmas Day opening. While the stars are on the East Coast, they'll promote the project with multiple TV appearances. Anne is set to chat with David Letterman and appear on Live! With Kelly and Michael next week.

Isla Fisher and Sacha Baron Cohen spent yesterday afternoon at a kids' birthday party in the park with their daughters, Olive and Elula. Sacha and Isla chatted with other parents in Santa Monica while the girls had their faces painted. Isla has been spending time close to home with her family since premiering her dark comedy Bachelorette in NYC last month. She'll be back in front of the cameras soon, however, with a guest-starring role in season four of Arrested Development. The cult series began shooting its return episodes back in August. Meanwhile, Sacha is also gearing up for a new project. It was announced last week that he'll star in a Paramount film based on the real-life story of a Hong Kong billionaire who offered a reward for any man who could woo his daughter away from her lesbian partner.

Chris Hemsworth and Elsa Pataky hit the red carpet in London last night for British GQ's Men of the Year Awards. Elsa and Chris had a kids-free night out on the town. Four-month-old India Hemsworth was at home, though she's often spotted traveling the world with her famous parents, recently visiting far-flung locations like LA and Madrid.

Elsa and Chris mingled at the bash with other celebs like Sacha Baron Cohen and Homeland's Damien Lewis. Stella McCartney also made the rounds with her husband, Alasdhair Willis. The whole celeb group was treated to a performance from NYC rapper Azealia Banks and jokes from hosts Jimmy Carr and David Walliams. Jimmy got things off on a cheeky note by saying, "Prince Harry would have been here tonight, but he didn't have anything to wear." Michael Fassbender took home a statue too as actor of the year.

Sacha Baron Cohen and his wife, Isla Fisher, had a breakfast date this morning in LA. The couple spent some alone time together after a family outing this weekend. Isla and Sacha accompanied their daughters, Olive and Elula, to a birthday party and endearingly carried the girls back to the car afterward.

The star couple is spending downtime on the West Coast for now. Sacha is coming off a press tour for his most recent project, The Dictator, and Isla will begin a string of promotional tours for her upcoming films. She has Bachelorette hitting theaters in September, followed by Rise of the Guardians, and news regarding her third and highly anticipated film was announced this week — The Great Gatsby's release date was pushed back from December of this year to Summer 2013.

Sacha Baron Cohen and his wife, Isla Fisher, brought their daughters, Olive Cohen and Elula Cohen, along to a kids' birthday party in Glendale, CA, yesterday afternoon. The girls had fun with their young friends snacking and checking out gifts, and afterward, Sacha and Isla carried them back out to their car. Sacha and Isla are hanging out on the West Coast after he wrapped up press for his latest movie, The Dictator. She'll be the busy one next with three films coming out this year. A trailer for Bachelorette, her September release, just came out, and she has the much anticipated The Great Gatsby due around the holidays. Isla's animated Rise of the Guardians is also out in November.
