Dianna Agron (Quinn) may have shot down those recent engagement rumors, but that doesn’t mean the Glee star and Alex Pettyfer, her boyfriend and I Am Number Four co-star, aren’t headed toward marital bliss.

"When they moved in together it was pretty clear how serious they were getting," a source told E! Online. Does that mean an engagement is in the cards? "That's the road they are headed, if they aren't already.” Sounds promising!
