Are Riya Sen and Upen Patel back together?

Haaye hai, what is this I'm hearing now? A little panchchi from Bandra tells me that Upen Patel is back in aamchi Mumbai and has hit the party circuit like a maniac.

And believe it or faint, he was apparently spotted getting cosy with Riya Sen at a Juhu nightclub on Thursday.

Officially they were there for the launch of a shoe brand. The Sen kudi definitely knows how to live up.
