Former Go-Go’s lead singer Belinda Carlisle may have bitten off more than she can cha-cha by accepting a spot on Dancing with the Stars.

According to People, the 50 year-old singer — the oldest contestant in the group — has one weakness.

“Spinning,” says Carlisle “I can’t even look at a merry-go-round without getting dizzy.”

Because of this prob, Carlisle and her partner Jonathan Roberts practice five hours a day, six day a week.

“I’ve never done anything so strenuous,” she confessed.

And despite her best efforts, Carlisle — who is the face of NutriSystem this year — is already losing weight from her tiny body despite “eating like a pig.”

Everyone should have such problems.
