They're both hot property in Hollywood and have recently come out of long-term relationships.
So no wonder Ashton Kutcher and Lea Michele were flirting up a storm at the premiere of their film New Year's Eve.
The red carpet outing was one of Ashton's first public appearances since splitting from his wife of seven years, Demi Moore.
But if the actor was feeling the pain of his recent break up, he hid it well as he got up close and personal with Glee phenomenon Lea Michele – his love interest in the ensemble piece.

The glossy brunette, who broke up with boyfriend Theo Stockman in September, giggled and laughed as the Two And A Half Men star showered her with attention.
With its plunging neckline, her daring silver dress had a magnetic effect on her co-star who pulled her close as they posed.
Lea seemed to enjoy the night, and later took to Twitter to relive the magic.
"I'm the happiest girl in the world tonight!!! Having the best time ever at the New Year's Eve premiere!" she enthused.
And there was, of course, praise for her co-star. "It was such an honor working with you. I cannot thank you enough," she told Ashton.
Meanwhile, the actor's estranged wife Demi has been keeping a low profile since she announced she was filing for divorce.
Recent reports suggest that she is being comforted by cosmetics businessman Scott-Vincent Borba following her separation.
And her Twitter posts suggest that she is keeping a positive outlook following the split.
"Why do we have only one day for giving thanks? Is that why so many people feel unappreciated? Make this one of 365 days of Thanksgiving! " she said over the recent holiday season.
