Jennifer Aniston and John Mayer were spotted at the Sunset Tower Hotel last night, and even though they quickly slipped into the waiting SUV, we were able to get a shot of the lovebirds together. We've got pics coming too, so stay tuned for those!

We're not sure if John is this chivalrous with all of his ladies (and it's quite a long list!), or if he's just trying extremely hard to win Jen back, but he opened the door for her on the way out. Is he just a nice guy, or is he kissing up to Jen?
