The comedian and talk show host turned 57 on Monday.

Happy birthday, Ellen!

Ellen DeGeneres turned 57 on Monday, and she kicked off her birthday celebration on The Ellen DeGeneres Show with a surprise visit from Vice President Joe Biden and a serenade from Keith Urban. DeGeneres also took the opportunity to announce several guests who would be appearing on her talk show over the next two weeks, including Kanye West, Olivia Munn, Jimmy Fallon, Kevin Costner, Sam Smith, Octavia Spencer, Sia and additional surprises to come.

The birthday announcements build on a year in which several A-listers have already stopped by her show, including former President Bill Clinton, Justin Bieber, Benedict Cumberbatch, Sam Smith and Jennifer Lopez, who expressed disapproval at being called a "cougar."

Fifty-six proved to be a successful year for DeGeneres. She hosted the 2014 Oscars (the most watched Oscar broadcast in over a decade), where her star-studded "selfie" with Meryl Streep, Brad Pitt and Jennifer Lawrence, among others, took Twitter by storm, quickly becoming the most retweeted photo of all time. DeGeneres continued her digital takeover with her launch of Ellentube, a video portal and iOS app for users to upload family-friendly content that can end up being broadcast on her talk show.

Since airing its first episode in 2003, The Ellen DeGeneres Show has grown to be one of the top daytime talk shows, earning a Daytime Emmy award last year for outstanding talk show, entertainment. Now in its 12th season, the TV show started airing same-day telecasts on Lifetime Asia this past October in countries including Hong Kong, Singapore and the Philippines.

This year, she's planning on increasing her small-screen footprint, inking deals to air three new shows on three different networks in 2015: an LGBT-themed comedy on NBC, a celebrity hidden-camera show on ABC and a designer competition on HGTV.
