Singer Katy Perry says she has two small rocks stuck in her knees, courtesy lots of surfing expeditions during her childhood.

 

 

 The 28-year-old, who is dating singer John Mayer, likes the feeling of rocks in her knees, reports contactmusic.com.

 

 "Growing up in Santa Barbara, I did a lot of surfing and skating and wherever I go I still have these two rocks that I still can't get out of my knees from being slashed across the rocks in Rincon, which is like a really popular spot in Santa Barbara, and the rip tides just slapped me against the rocks and forever I've had these rocks in my knees," Perry said.

 

 "I kind of like it, I feel, like, closer to earth," she added.
