Kristen Stewart Catches a Concert With Katy Perry's Assistant

Kristen Stewart had a night out with friends when she attended a concert in Hollywood on Sunday night. She was joined by Katy Perry's assistant, Tamra Natisin, as she left Hotel Cafe and piled into a car with a group of pals. Kristen recently injured her foot when she stepped on a piece of glass and had to attend last week's Oscars in crutches. Kristen's injury made Daniel Radcliffe nervous when they stepped out on stage to present an award together. Daniel told E! News, "I just wanted to pick her up, put her in my arms and carry her onto the stage."

Robert Pattinson wasn't with Kristen when she hit the town yesterday, since he is still in Australia filming The Rover. However, Robert Pattinson was with Kristen Stewart in a way last week when she stepped out wearing his t-shirt after the Academy Awards.
