A source close to 'Twilight' co-stars and real-life girlfriend/boyfriend Kristen Stewart and Robert Pattinson says that although they’ve hit a bit of a rough patch, they're still very much together. At least today.

Now that the red carpet premieres of the 'Twilight' movies are over, you don’t see them together in public much anymore, but they were recently snapped candidly enjoying Coachella together. They also recently celebrated Kristen’s birthday together with the exchange of a very expensive - errr - pen, and spent some time coupling it up in New York.

We don't hear much about them as a couple these days, but according to a source for E! News, “They are absolutely still together but are having some difficulties right now.”

Which explains why poor Rob had to celebrate his birthday quietly while Kristen stepped out at the Met Gala. She was planning a party, but somehow it fell through.

The problem, according to the source, is “priorities,” but the notoriously private pair seem to be working through it. The source wasn’t concerned, saying, “They'll be fine ... I do not foresee a split, they are just crazy in love. This is just another bump in the road.”

And, hey, we’ve seen them survive bigger bumps than priority differences. Still, since their return to L.A., another insider said Rob’s “been hanging out with the boys a lot, and [Kristen has] been with her girlfriends ... They seem to be living separate lives at the moment."
