This Tuesday is a huge day for Gleeks everywhere as the show’s Valentine’s Day special debuts on TV. Tonight, the cast is set to cover treasured love songs including Whitney Houston‘s “I Will Always Love You” and Gym Class Heroes‘ “Stereo Hearts.” 

To celebrate this special holiday, Celebuzz is taking a look at who has been stealing smooches from one of our favorite Glee gals. We know Dianna Agron has wooed Cory Monteith and Mark Salling on the show, but has the actress had any luck offscreen? You betcha!

In the past, Dianna has been linked to hunky actor Alex Pettyfer. The two became an item soon after they finished filming I Am Number Four together. The co-star couple split in 2011.
