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.

'Glee' has understandably commanded its fair share of headlines in recent months, even as the series is poised to wrap up its final season in 2015, but it seems longtime fans of the series have some seriously good news: the upcoming 100th episode will feature the returns of most of the original cast, including repeat guest star and Broadway sensation Kristin Chenoweth.

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.

Dianna Agron and Alex Pettyfer, the co-stars from the movie I Am Number Four (in theaters February 18th) are engaged. Congrats to the happy young couple . I suppose you can say that the director D.J. Caruso is the matchmaker on this pair...
