Leonard, Penny, ‘Big Bang Theory’ Wedding?

Leonard accidentally ask Penny to marry him during The Big Bang Theory's Fifth season and she turned him down. The neighbors remind a couple, sometimes on the DL, but they could soon take it to the next level.

Johnny Galecki tells The Hollywood Reporter that the geek squad will soon shoot a Valentine's Day episode. Galecki, who plays Lennard, added "It's a big one for Leonard and Penny -- there might be somebody getting down on one knee."

Let's start the planing the wedding now. Sheldon would be best man of course. But I think Kripke and Stuart would make make funnier groomsmen. Oh and Sheldon and Leonard's mom have to sing a duet at the reception. 'Baby Hold Tight!"
