Tonight's the night! Britney Spears fans everywhere have had this day marked on their calendars for months, anticipating her debut as a judge on The X Factor. With the new gig, Brit Brit is out to prove she hasn't lost it—and she's one step (or gallop!) closer to that goal with her latest appearance on Ellen. The pop star had tweeted her love for the Gangman dance, Korean performer Psy's viral dance craze video (which currently has more than 150 million views!), and when Ellen got wind of it, she invited both of them onto her show so Britney could officially learn the boogie. Enjoy the clip, and be sure to tune in to Fox tonight at 8 p.m. EDT to see Britney in action on The X Factor!
