Beyoncé Knowles posed backstage at a Brooklyn Nets basketball game, marking her first foray into the world of Instagram! Bar Refaeli piqued our interest with her picture, sharing a shot of herself drinking from an eggshell. Usher and his little one, Naviyd Raymond, spent some sweet father-son time together, and Nicole Richie horsed around on a ranch.

Kristen Stewart joined costar Garrett Hedlund and On the Road director Walter Sales for a screening of their movie in NYC on Thursday evening. She's been in the city to help promote Breaking Dawn Part 2, but she was able to take a break and focus on her indie project for the night. Kristen showed off a new clip from Breaking Dawn to Jimmy Fallon on his show earlier in the week, and last night it was her boyfriend and leading man Robert Pattinson's turn to chat on the late-night show. Kristen Stewart's style has been daring — and leg-baring! — so far during this final Twilight press tour, and all eyes will be on her when she and the rest of the cast have their official premiere in LA next week.

Andrew Garfield and Emma Stone had a lunch date yesterday at the La Super-Rica Taqueria in Santa Barbara, CA. They hung out in the town two hours north of LA for a bit of fun before Andrew heads east in the coming days. He's expected as a guest of honor at the Worldwide Orphans Foundation gala next week. The annual event brought both Andrew and Emma out onto the red carpet last year too. Emma and Andrew have enjoyed some downtime together recently during a joint hiatus from moviemaking. They were able to mark Emma's 24th birthday, which was Tuesday, and clearly, the celebrating continued on their getaway.

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!

Elle Fanning wore Dolce & Gabbana to join Christina Hendricks at a screening of their movie Ginger & Rosa at The Paley Center in LA last night. Christina also opted for a long dress, and apparently she and Elle have a similar taste in clothes. Elle told us she and Christina bonded over shopping, saying, "She loves vintage just like me. We share the love of that — she looks amazing."

Elle also had kind words for her costar in another project, Maleficent, Angelina Jolie. Elle admitted to being nervous when she first met Angelina. She told us last night, "I remember going into Pinewood Studios and turning the corner in London, seeing her for the first time and thinking, 'There she is!' And she immediately just gave me a huge hug. And she said, 'We're going to have so much fun working together!' From that moment I was like, 'Oh my God — she's touching me!'" Angelina and Elle won't be on the big screen together until 2014, but Elle's Ginger & Rosa is in select theaters now.
