The Tonight Show

Last night Jennifer Lawrence slipped into a body-hugging gray dress by Alexander Wang for an appearance on The Tonight Show. She chatted with host Jay Leno about her latest release, Silver Linings Playbook, which is out tomorrow, and shared a funny story about her obsession with Honey Boo Boo.

Later in the evening, Jennifer changed into a black Christian Dior number for the LA premiere of Silver Linings Playbook. There, she met up with costar Bradley Cooper and posed for photos with the entire cast. Early reviews praise Jennifer and Bradley for their onscreen chemistry and Hollywood insiders are already buzzing about possible Oscar nods for both actors.

Kristen Stewart was smiley and happy as she stepped out in a colorful Peter Pilotto dress to chat with Jay Leno for The Tonight Show in LA on Monday evening. Kristen spoke to Jay about the final Twilight movies, Breaking Dawn Part 1 and Part 2, saying, "Popped one out — pretty concerned with that. Me and Edward are doing quite well; people keep trying to kill my baby. But I'm now superspectacular, so I can take care of that, being a vampire." Kristen also touched on Breaking Dawn Part 2's twist ending: "Every time I see it or even think about it, I get giddy. It freaks me out. . . . It's easy to skim over. But you can find the root of our little twist [in the book]." Kristen switched gears from her blockbuster franchise to promote her indie project On the Road over the weekend. Kristen premiered On the Road at the AFI Festival in LA on Saturday, and she was joined by boyfriend Robert Pattinson at that afterparty. While Kristen was chatting with Jay, Rob was elsewhere in town making his own appearance on Jimmy Kimmel's show.

Miley Cyrus wore a unique ensemble for her Friday chat on The Tonight Show. She and host Jay Leno were together to talk about her small role on Two and a Half Men, but chat veered toward her eye-catching Anthony Vaccarello bustier and Moschino maxi skirt combo. She also chatted about her upcoming album and shared a sneak peek at one of her "backyard sessions" in which she tests out new music. The clip she previewed was special, since right after recording it, Liam Hemsworth proposed! Miley said, "That's one of Liam's favorite songs — he asked me to marry him 20 minutes later. So while I was singing it, I had no idea! He was looking at me funny! And then I knew."

Kristen Stewart rocked flats for her interview on The Tonight Show With Jay Leno that aired on Friday evening. She assured Jay and the audience her choice of footwear wasn't because she wanted to get out of wearing heel. Kristen apparently suffered yet another injury while filming her Breaking Dawn Part 2 reshoots in Vancouver this week. The "puncture wound" came while capturing even more of Bella's first hunt as a vampire, which Kristen says will be awesome when the movie hits theaters in November. Now she's switching gears to promoting Snow White and the Huntsman and she'll be heading to London next week for the junket — where she'll meet our lucky I'm a Huge Fan winner! — and premiere. First up, however, she's rumored to be making a stop off at the Met Gala in NYC on Monday.

Jennifer Aniston wore all black to visit with Jay Leno yesterday on The Tonight Show. Jen spoke about her new dog Sophie in addition to her just-released movie Wanderlust. Jay was also curious to know about how Jen became such close friends with Chelsea Handler. Jay asked if Chelsea's really as into drinking and being nutty as she seems on TV. Jennifer hit back saying, "That's her public persona. She's so not that crazy. She's one of the nicest, most generous — why am I getting so defensive? . . . I met her at my 40th birthday party. She crashed it! No, she was very much invited." Jay and Jen went on to discuss their mutual interest in the show Hoarders, and their own tendencies to hold on to objects for far too long.
