Jennifer Lawrence

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.

Jennifer Lawrence and Nicholas Hoult had dinner at The Little Door restaurant in LA on Monday night, stirring up rumors that they may be reuniting as a couple. The former couple apparently had a spot in the well-known restaurant all to themselves; a source tells POPSUGAR Jennifer and Nicholas has "a private room all to themselves." Jennifer showed off her new short haircut and held on to a copy of Anna Karenina as the former flames made their way out of the back exit and drove off in her car together.

Jennifer and Nicholas met on the set of X-Men: First Class in 2010 and dated for two years before parting ways in January 2013. In spite of the breakup, Jennifer bounced back in a big way — she went on to become an award-season darling and a member of the A-list set while taking home an Oscar for her role in Silver Linings Playbook. While it hasn't been confirmed that Jennifer and Nicholas are linked up romantically, they are likely seeing a lot of each other on the set. The pair is currently filming X-Men: Days of Future Past along with Hugh Jackman, Halle Berry, and Anna Paquin, in addition to Jennifer's other big-screen projects. She spent time in Boston earlier this month while shooting American Hustle with Bradley Cooper and will gear up later this year to promote Catching Fire ahead of its November release.

Jennifer Lawrence touched down at JFK Airport in NYC last night after catching a flight out of LA. She is back on the East Coast after making big news with her date night with ex-boyfriend Nicholas Hoult earlier this week. Jennifer reunited with Nicholas for dinner at LA's Little Door restaurant on Monday evening. The pair's night out has stirred speculation that Nicholas and Jennifer have rekindled their romance after breaking off their two-year relationship back in January. Even after the couple called it quits, Nicholas spoke highly of his ex on the heels of their split. The two were smart to keep things amicable, as they are preparing to film X-Men: Days of Future Past, the sequel to the film which brought them together back in 2010.

Jennifer Lawrence and a friend shopped at Vera Wang's LA boutique Saturday. As they left the shop, Jennifer's new lob haircut was on display, though partially obscured by her black hat, the finishing touch to her outfit, which included a knotted gray tee, fringed bag, and long black skirt. She's back in California following a stint in Boston, where she worked on American Hustle, the new David O. Russell movie, with Bradley Cooper and Jeremy Renner. Amy Adams and Christian Bale round out the cast in the film, which is the story of a 1970s financial scandal that brought down multiple members of Congress.

It was an exciting week for celebrities, between getaways and red carpet appearances. Pregnant Kate Middleton donned a patterned dress for a school visit in Manchester, England, while Gwyneth Paltrow got sexy in a sheer gown for the LA premiere of Iron Man 3. Beyoncé Knowles showed baby Blue love on a lunch outing in Paris, and David Beckham got kisses from his daughter, Harper, during a father-daughter stroll in London.

Jennifer Lawrence soaked up the LA sunshine on a brunch outing with friends at Tavern restaurant in Brentwood yesterday. She wore a sheer maxi skirt and showed off her new hairstyle after debuting the shorter look on the red carpet at the GLAAD Awards on Saturday night. Jennifer asked for a bob from stylist Mark Townsend hours before the event, and the style is already turning heads. She'll be back to the longer updo she's been sporting on the set of American Hustle soon, though, since production is under way again in Boston following a break during last week's manhunt for the Boston Marathon bomber.
