A few websites are reporting Kristen Stewart and Rob Pattinson are headed towards yet another break up, but then why is she carrying his brown puffer coat?!

On Saturday evening K. Stew was snapped flying in to Los Angeles International Airport from New York, and she was wearing her uniform of jeans, a tee and a cap, looking like her usual glum self. But back to that jacket! Rob was last seen wearing the coat at the German premiere of Breaking Dawn in December, so it looks like he let her hang onto it while they were apart for the last week or so.

While Rob will be busy with several films this year, Kristen is set to begin work on Focus, but she won't be starring opposite Ben Affleck. Last week Ben explained why he quit the flick, telling MTV News, "Basically I'm doing this movie called Live By Night and I'm trying to meet this schedule ... so that I can have it released at the right time. And basically I haven't gotten enough writing done; it became clear that if I took that job — it was in Buenos Aires for three months — I'd have to miss the deadline. I had to choose between getting the movie out when I wanted to or doing that movie ... Reluctantly I chose the latter but I love those guys, I love Kristen. I was really excited to work with her. I think the movie is going to be fabulous. I'm sure they'll find a great guy for it."

Hmm, think Jennifer Garner influenced his decision at all?
