Coy cougar? 

Kirstie Alley revealed the "mystery man" she's been hanging out with in Paris: it's former So You Think You Can Dance contestant Serge Onik!

"Mystery man and I slink out of Paris today to covertly take Rome by storm," the 60-year-old tweeted Thursday. "Stay tuned. Cougar Maximus or just friends? I love my silly life!"

Onik, 23, tweeted back at the season 12 Dancing with the Stars runner-up: "Mystery man loves you one more. One more show left on this crazy ass road show!"

The duo are partners for Dance With Me's traveling showcase and have been touring Europe together. The Fall Fantasy Showcase comes to NYC Oct. 30. "I won't be the best dancer in the show, but perhaps the funniest!" Alley wrote.

On Thursday, she tweeted that she was "homesick," but said the partners "have helped raise of 5 million euro for charities."

"He has been an awesome dance partner and fearless friend," she added.

Alley has lost 100 lbs. since she started her stint on ABC's Dancing with the Stars, but don't expect her to settle down with a man anytime soon. 

"This is what I think about sex," she told Entertainment Tonight last month. "I think its fun to hookup every night for six months... Then it's time to move on!"
