Happy Valentine's Day, Gleeks! It's that special day when you spend the evening with your special someone  or maybe you spend it on the couch by yourself eating pizza in your jammies. Either way sounds pretty darn good to us! But which of our favorite Glee stars are in a relationship, and which ones are single and looking to mingle? 

Actually, one Glee star's relationship status just changed recently, as Dianna Agron (Quinn) has split from Australian restaurateur Nick Mathers, whom she'd been dating since last year. But she should fret not, as plenty of her Glee co-stars are still looking for their perfect someones, too.
