While the two may have dined together at Jerry's Deli in L.A. on Friday, they are "just friends," sources confirm to us.
In fact, Mr. Monteith was spotted later that same night, looking quite cozy at West Hollywood hot spot Voyeur with a mystery blonde...
"Cory showed up to the club with a girl who definitely looked like his date," an eyewitness tells us. "Mark Salling showed up with the two as well, but Cory spent the evening attached to the girl at the hip."
We're told Monteith and his lady friend spent most of the night holed up in a corner, where the Glee star gave the gal cute kisses on her forehead throughout the evening. "They looked like they were into each other and having fun," our spy says.
We're told the two left the club and hopped into Monteith's black Honda Civic at about 1:30 am.
Even so, one of our sources close to Monteith tells us the TV hunkster is "not exclusive with anyone at the moment."
And while we don't know if he has any plans to ask a lucky lady to be his Valentine, we have a feeling it won't be happening. Monteith has made it perfectly clear that he's no fan of the heart-filled holiday.
