At last ... the Britney Spears we know and love is back!

In her new video for "I Wanna Go," the 29-year-old pop princess is showing off her fabulous body and incredible moves while attacking the photographers with her microphone. Fierce!

We're lovin' the not-so-subtle spoof on her relationship with former lover/photographer Adnan Ghalib. Gotta love Brit's sense of humor!
