Former 'N Sync star Lance Bass' Dancing With The Stars partner Lacey Schwimmer has become the second professional on the hit show to be diagnosed with endometriosis.

Julianne Hough was diagnosed with the painful medical condition, which wreaks havoc on the appendix, pelvis and abdomen, two weeks ago, and has since had surgery.

Now it's pretty Schwimmer's turn.

She tells The Insider, "A few days ago, I started feeling very shaky, very weak, and I had awful cramps-- I didn't really know what was going on. I went to go get checked out and I actually have the beginning onset of what Julianne has. It hurts very bad. Right now I'm insanely weak, and the room is spinning (but) I have medication that is taking care of it. We caught it at a very good time."
