Double the hotness!
"True Blood" hunk Joe Manganiello showed off his incredible physique on the beaches of Hawaii today -- where he was spotted alongside a beautiful, busty blonde.
We have no clue who the mystery gal is -- but we don't think it's his former fiancee Audra Marie.
Whoever she is, one thing's for sure: They're one good-looking couple!
Prepare to see a lot more of Joe in the upcoming flick "Magic Mike," where he plays a male stripper.
