In hockey terms, this would be known as a face-off.

Glee costars Lea Michele and Cory Monteith, whose characters may soon be married on the show, engaged in some real-life PDA at Madison Square Garden on Wednesday – smooching their way through a playoff game between the New York Rangers vs New Jersey Devils.

Michele, 25, and Monteith, 30, at times seemed blissfully unaware of the action on the ice, preferring to keep each other warm in the stands.

Speaking of scoring, the Devils put away the winning goal in the third period to win the game 3-2.
