EXCLUSIVE PHOTOS - Lady Gaga Slums It At Boyfriend's California Beach Shack

Lady Gaga may be an international superstar, but that doesn't mean she can't rough it at her boyfriend's tiny beach house once in awhile!

The Lady was spotted looking comfy in a black oversized tee, dark shades, and her blond hair tucked in a bun, while watching Vampire Diaries star Taylor Kinney do the laundry and pick up some groceries around his California pad, on MLK Day.

An X17 photographer on the scene tells us:

"Gaga and her boyfriend seemed happy -- they were just living simply. It's like she's this rich, successful mega-star and all she really wants is a simple life."

The "Bad Romance" singer usually stays mum on her personal life, but she gushed about Kinney back in September, "You know I don’t talk about my love life, but I’m very happy."

Gaga was seen house hunting in her beau's hometown in Pennsylvania, and is reportedly interested in a $1.7 million dollar property that caught her eye. Pack your bags, Taylor!
