On Friday Kristen Stewart was snapped out with boyfriend Rob Pattinson's friends for the second night that week, and we're guessing her mysterious foot injury might have occurred shortly after these photos were snapped! (After all, on Saturday it was reported that K. Stew was on crutches at the Oscars rehearsal.)

Kristen partied with Rob's pals, including Marcus Foster and his bandmate Jack Standen, and she was seen running around on the sidewalk, laughing and riding around in another man's arms. Hmm, if it's true that she's having problems in her relationship, this isn't the best way to show Rob how serious she is about staying together!

On Sunday Kristen ran into Anne Hathaway backstage at the Oscars, and when the Best Supporting Actress winner spotted her crutches, the Twilight star said, "I know, I'm an idiot ... But congratulations!"

"Please tell me you're going on stage with those [crutches]," Hathaway said. "Nope," Stewart replied. "I'm gonna hobble." Hathaway joked, "Well, break a leg ... Oops!" Stewart then revealed that she cut her foot recently after stepping on glass. "I just hope [the wound] doesn't open up right now."

Stewart's manicurist added to Us Mag, "She had sliced her foot and everyone was worrying about would she wear heels or flats or one heel, crutches or no crutches. She tried so many options, she was really a trouper."
