The timing is worth noting -- Tyler was havin' a good time with Alex and co. the day we learned about hissplit from the "Pitch Perfect" star. According to sources close to them, the breakup had more to do with distance than the cheating rumors.
Sources close to Tyler, a former pro surfer, tell us there's nothing going on between him and Alex -- claiming it was just a group of 6 out to dinner. But, the eyewitnesses say, something's fishy about that, and it wasn't the sushi.
As for the close whiff, we're told they were all smelling each other's perfume and armpits over a discussion about scent and deodorant ... yeah, right.
