We've all done it at some point. You're dating somebody, you sleep over their apartment, and you accidentally leave a favorite t-shirt or pair of jeans. It's a little risky. If a breakup happens, you could lose one of your favorite shirts forever. Have you ever wondered what ever happens to those lost articles of clothing? Have you ever even considered that maybe your ex was WEARING your clothes? It looks like that's what happened to Twilight star Robert Pattinson. His co-star, and ex GF, Kristen Stewart was seen wearing one of his t-shirts as she was catching a flight at LAX yesterday.

The NERVE!  Give it back!  You cheat on him, then wear his t shirt?  Too much.
