That's exactly what happened today, we've seen the pics (thanks to our friends at Pacific Coast News) that prove it!
Walking out of her house and into a car with his guitar in hand, Ed was photographed leaving Sel's crib.
Sooo, do you think the two celebs were making music together or are they really more than just friends?
We think they were probably just making music (especially because he had his guitar with him( but really, how awesome would an Ed and Sel relationship be?! We would be shocked though because he did tell us on Twitter a few weeks ago that they're good friends.
Hmm! What do you think?
