But let's not get too carried away, because this could just be a rabid Twilight fan...

An Instagram account claiming to belong to Kristen Stewart started posting photos in the middle of the night, and a number of news outlets are speculating that the 24-year-old actress has finally made a public profile on the social media app. The first post shows K. Stew and two friends and reads, "Hello Instagram." However, the other photos appear to be old, and there's one shot of a fancy braid with the caption, "Miss my hair." Seeing as K. Stew has been rocking a very short 'do and grubby duds for the better part of the last year, we have a hard time believing that she's grown reminiscent of her more glam looks...

In October, K. Stew revealed that she did have an Instagram account, but it's for her inner circle. "I have a private Instagram so I can keep in touch with my friends because I’m always away," she said in an interview with USA Today. "That’s not social media. We have a shared photo stream."
