Ellen Degeneres

Harry Styles, Anna Kendrick, Katy Perry and more stars react to the U.S. Supreme Court's historic decision.

'Pitch Perfect 2' star Brittany Snow showed the world her 'Gangsta's Paradise' rendition on 'Ellen.'

Madonna posted a photo of herself stealing a kiss from Justin Bieber while both were backstage filming The Ellen Degeneres Show.

Watch Barack Obama read mean tweets on 'Jimmy Kimmel' while Michelle Obama dances to "Uptown Funk" on 'Ellen.'

Just a few days after his humbling appearance on 'Ellen' last week, Justin Bieber once again made a surprise appearance on the show.

Sigh. 'The Tonight Show' temporarily moves to Los Angeles -- Hollywood, Tinsel Town, The Big Grapefruit, only one of those is a real nickname -- and is suddenly just flooded with random star power. Zzzzz.

Earlier this month, Kanye West unveiled a collaboration with the great Paul McCartney on a song called ‘Only One.’ Today, the rapper premiered a video for the song on ‘Ellen.’

We’ve mostly stayed away from any ‘Two and a Half Men’ hubbub since Charlie Sheen’s crazy days settled down, and Angus T. Jones similarly talked himself out of a job, but with the CBS comedy’s series finale firmly set for February 19, we’re at least curious if Charlie Sheen can negotiate a return appearance. Judging by Ashton Kutcher’s coy performance in a recent ‘Ellen’ interview, that looks to be the case.

Chris Pine Serenaded one very lucky fan with Frank Sinatra.

Matthew McConaughey has a few new television commercials out for Lincoln.  One commercial in particular stands out from the others.  We only see the edited version on tv, but Ellen Degeneres shows us the full cut. LOL!!!
