Stars were out in full force on Twitter to send their 30th birthday wishes to the Pop Princess, including Will.i.am, Miley Cyrus, Ellen DeGeneres and Paris Hilton. Hundreds of fans also sent their wishes, to which Britney replied, “Having an incredible birthday – thanks to my fans for all the amazing wishes & videos!... I love all of u!!!”

Britney has come a long way after her breakdown in 2007, which saw the singer shave her head, attack a car with an umbrella, go to rehab and lose custody of her kids to Kevin Federline.

Friends feared she would not reach this age, but she has turned her life around, regained access to her children, and got back into performing. Here’s to the next 30!
