Lady Gaga strips down!

Lady Gaga has revealed how she stripped down and streaked through an LA hotel to celebrate her 25th birthday.

She told the Sun newspaper: "I had this funny moment after my 25th birthday where I woke up alone and naked in a hotel room in LA. I had no clothes in my bedroom and had to run to the closest room.

"I had a look if anyone was around and ran across the hallway. I felt like a six-year-old girl who's hiding from the universe hoping no one will see her."

Gaga revealed the video to latest single Judas earlier this week.
