Less than a year after director D.J. Caruso set them up, I Am Number Four costars Dianna Agron, 24, and Alex Pettyfer, 20, are engaged, a source tells UsMagazine.com. Although the couple have remained mum on the news, both of their reps claimed to E! News that the report is "not true."

"[Agron] is an amazing woman, and she's got this old school, classic movie-star elegance to her," Pettyfer gushed to Ellen DeGeneres on her show last week. "I'm just very happy in my personal life."

And in a recent Sugar Magazine interview, the Glee star explained why things work with her British beau.

"Alex might see himself as a bad boy, but he's actually very sweet in real life," Agron said. "It's important to have your differences in any relationship. I wouldn't want to be dating a carbon copy of myself. That would just be boring."

She looks like she's 14. And on Glee, show sucks.

She's so pretty. I hope I Am Number 4 does well because she's a good actress. He's hot too but too young for her.

While he's certainly nice-looking, this is about the most depressing news since Jessica Alba got hitched to whatsisface. I, too, am on the 'Dianna + Lea' team, and I'm a straight male...

They are a beautiful couple. Maybe he just bought her a nice ring. I got married at 22 and am still very happily married 23 years later. Maybe he's mature for 20? Who knows. Besides you can be engaged as long as you want, it doesn't mean they are getting married tomorrow, if it is even true.

Publicity stunt for the movie.

Not engaged. Both reps denied it yesterday. They never even confirmed they were dating.

Wow, 20 and 24. Yeah, that should last a lifetime.

I seriously don't believe it.. apart from the fact that in my mind she's Lea's girl, she's just too traditional to get engaged so fast.

Huh??? Weird! Congrats...I guess?

Dianna & Lea... 4eva :)

I don't know if I believe this. They just don't seem like the type to get engaged so fast.

they look like cousins
