Britney Spears Celebrates 35th Birthday With Hits (And Cake) During KIIS Jingle Ball

If there's one thing Britney Spears has always remained consistent with during her almost-two decade career, it's her adoration for her loyal fanbase, so it doesn't come as much of a surprise that the pop titan rejoiced with the Britney Army for a hits-filled set during her 35th birthday on Friday night (December 2) in part of iHeartRadio's Jingle Ball Tour.

Much like her set at the iHeartRadio Music Festival in Las Vegas, Spears brought the glitz, hits and skin for the almost-30 minute set at the Staples Center in Los Angeles. Donning a midriff bearing white top with feather arms and black shorts, Spears kicked off her birthday set with 2013's "Work B*tch," before venturing into pop gems like "Womanizer," "I'm A Slave 4 U," "Toxic" and, of course, "Make Me" off her recently-released LP, Glory.

Even though Tinashe appeared as the special guest for the first time collaborative performance of Spears' new single, "Slumber Party," the real viral moment arrived when Miss American Dream was presented with a birthday cake from Ryan Seacrest and a string of other radio personalities after her set. "Awh. Thank you guys so much. It's been real," she bashfully told the crowd. After all, even Diplo agreed that the night belonged to B.
