Dianna Agron

You'll never guess which stars once shared spaces with the likes of Justin Timberlake, Kristen Stewart, and Robert Downey Jr...

From amicable splits to bitter ends, these are some of the most surprising love triangles involving celebrity friends.

We're celebrating the 'Glee' alum's 30th birthday today (April 30) with lesser-known facts about the starlet.

February 14th can turn more bitter than sweet, which was certainly the case for the V-Day Hollywood breakups we've rounded up here.

Dianna Argon will be making her British stage debut in a new play about the late designer Alexander McQueen.

We crush pretty hard on some of our favorite celebs, but is our affection worth $23,000? One man attending a charity auction in Switzerland decided the answer to that question is "yes" -- at least when it comes to ‘Glee’ actress Dianna Agron.

Dianna Agron fans were certainly in for a surprise when the 'Glee' actress posted a topless shot from a recent photo shoot on Twitter yesterday, Oct. 1.

It's in like Quinn! After being noticeably absent for much of Season 5 of 'Glee,' including the Cory Monteith tribute episode, Dianna Agron will return to the series as Quinn Fabray for the 100th episode.

Last night, 'Glee' aired 'The Quarterback,' its long-awaited tribute to Cory Monteith. It was both a beautiful testament to Monteith himself, and his character, Finn. One crucial character did not appear in the episode, however: Dianna Agron, who played Finn's girlfriend, Quinn, on the series.

Though Dianna Agron wasn't invited to Cory Monteith's tribute episode, she still holds her onetime 'Glee' costar close to her heart. The starlet, who likely won't be returning to the show at all, appeared on 'Katie' to promote her new movie, 'The Family' and wax poetic about her fallen friend.
