STEVEN TYLER wore a Speedo and banged on drums with his rumored girlfriend during a recent vacation in Maui… and there’s a video of all the action.

The 64-year-old “Aerosmith” frontman and former “American Idol” judge was spotted having a bangin’ time at Maui recently as he played the drums for a big group of other scantily-clad hippie-type party people.

But if you think they were being entertained by Steven Tyler‘s actually pretty awesome drum playing, think LOOK again because it could also be his very distracting black mankini (or man boobs) that was stealing their attention.

It was too distracting that we almost missed the fact that his rumored blonde rebound chick-he reportedly split from his fiancee, Erin Brady-was just behind him.

Here’s the revealing video… You know, if you’re into that sort of thing:
