Late Night with Jimmy Fallon

Justin Bieber made a stop by Late Night With Jimmy Fallon last night in NYC. Justin and Jimmy touched on many topics, starting with Justin's regular run-ins with the police thanks to his tinted windows. He joked, "Police really like to pull me over." At the moment, though, Justin's in a good place. He added, "I'm having fun being 18, enjoying my life, and being responsible." Justin went on to flash his abs during his appearance and share a kiss with a mannequin, which was being used in place of a basketball for a shoot-out.

Justin Bieber is spending time in the Big Apple ahead of his hosting gig on SNL this Saturday, Feb. 9. He will also give a live performance on the show, and recently debuted a new promo video. Justin has also been making headlines for his recent breakup with Selena Gomez, though the two reportedly reunited for a night together in LA over the weekend.

Tom Cruise got into a water war with Jimmy Fallon when he dropped by Late Night in NYC yesterday. Tom, who appeared on the Late Show the previous night as part of his promotion for Jack Reacher, first sat down to chat with Jimmy about giving their mothers Christmas gifts. After Jimmy talked about how he once gave his mom a food processor from a local drugstore, he asked Tom if he ever gave his mom something nice "like that." Tom and the audience started to laugh, and he said, "Actually, I do think I got her a food processor. I remember, I wrapped it in a house." Later, Jimmy invited Tom to take part in their water war skit, where Jimmy and celebrities do battle by trying to drench each other with water. Tom won the water war and earned the privilege of spraying Jimmy with a powerful water cannon.

Anne Hathaway kept to another tight schedule in NYC last night. Les Misérables star Anne first stopped by the studios of Late Night With Jimmy Fallon to chat about landing the role of Fantine, the same part her mother played in a stage production more than 20 years ago. During her visit to Late Night, Anne happily agreed to join Jimmy for a sing-along. Anne and Jimmy played Mad Lib Christmas carols, replacing key verbs, nouns, and adjectives with words randomly picked by the studio audience — check out their hilarious holiday-inspired duet! Later on, Anne supported her Les Misérables costar Hugh Jackman as he accepted an honor from the Museum of the Moving Image.

Despite the late one out on the town, it's likely Anne was up early this morning as the SAG Awards nominations were revealed. Les Misérables took home four nominations, with Anne earning a nod for outstanding performance by a female in a supporting role, while her other 2012 blockbuster, The Dark Knight Rises, was recognized for outstanding performance by a stunt ensemble — see the entire list of 2013 SAG Awards nominees!

Katie Holmes showed off her fun side during a visit to Late Night With Jimmy Fallon yesterday. She swung by the show to talk about her Broadway play, Dead Accounts, which is open in previews now. Katie and Jimmy also got down to business with a few minutes of charades. Jimmy also asked Katie about the possibility of a Dawson's Creek reunion with her former costars Michelle Williams, Joshua Jackson, and James Van Der Beek. She said, "I love everyone from the show . . . we have kind of talked about it here and there. But we're like, 'What do you do?' Because our last episode, Michelle's character passed away. Maybe we'll go on vacation — that will be fun — and just film it!"

Robert Pattinson brought his Breaking Dawn Part 2 press tour to Late Night With Jimmy Fallon last night. It's been a busy few days for Robert with stops on The Today Show and Live With Kelly and Michael. Kristen Stewart's been plenty busy too. She has visited the same programs to talk up the Twilight finale, but she's also doing double duty promoting On the Road. Last night, Kristen wore a leather LBD for a special screening of her big screen adaptation of the Jack Kerouac novel. Robert, meanwhile, chatted with Jimmy Fallon about his last go-round as Edward Cullen. They also had a bit of fun — Jimmy and Robert engaged in a water war!
