After a few seconds on Ed, you can see that he's getting his sing on with Bridgit Mendler AND Victoria Justice. In the clip, Ed strums away on the guitar. He sings first, then the ladies join in. Of course, there are a few tongues and goofy faces thrown in there, too.
We can't help but wonder...uh, why weren't we invited to this party? Seriously other than us, the only person(s) missing is Taylor Swift.
Watch the crew get down to some Brit Brit below. Love it!
