(People.com) -- Sure, costars on another popular show are dating in real life -- to the delight of fans -- but that's not the case for Glee's Cory Monteith.
The 27-year-old star's onscreen chemistry with Lea Michele, 23, is just an act.
"We're great friends," the actor, who plays McKinley High's quarterback Finn Hudson on the FOX show, said Thursday at the Marshalls and T.J. Maxx "Carol-Oke" contest at New York's Bryant Park. "We've become really close over the show, but we're just friends. We're not dating."
On Glee, Monteith's Hudson and Michele's neurotic and self-proclaimed star Rachel Berry are involved in a complicated love quadrangle that also includes former Cheerios cheerleader Quinn Fabray (Dianna Agron) and footballer Puck (Mark Salling).
It's messy with pregnancy, lies and two baby daddies for one baby. Confused? So are their characters.
"That seems really difficult. That seems like it would be tricky," Monteith said.
Salling, on the other hand, only wants to keep the rumor mill running.
"It's all true. Every little word is true," he said of the behind-the-scenes relationship stories. "Every little thing you read in those magazines is true. Spot on."
