Miles Teller and Model Girlfriend Hit the Beach in Hawaii

Miles Teller's girlfriend, Keleigh Sperry, got a tight grip on an inner tube and her man for a day on the beach.

The couple, who've been going strong for 3 years, beelined it to the sand while on vacay in Maui.

Miles packed on some muscle for his role in "Bleed for This" and looks to have enough left to pass for a lifeguard. He's come to the rescue before, after all.
