30. Radar (2009)
"Radar" was originally on "Blackout", but was added a a bonus track on "Circus" because it deserved to be released as a single. The song seems like it should involve some scorching nightclub action, but the video goes in an entirely different direction: a polo match.
The video is set in a countryside pony palace, where Britney’s boyfriend Paul is partaking in some polo. Paul seems nice enough, but as they’re walking through the stables, Britney catches sight of a shaggy-haired polo player. He’s on her radar.
She checks out shaggy guy as he’s playing polo, and gives Paul an awesome disgust face as he attempts to placate her with a diamond necklace.
Watching the game, Britney shoots seductive glances at the shaggy guy, which angers Paul. Paul’s team wins, and as he celebrates with the massive trophy, he notices Britney is missing. Of course, she’s off with shaggy guy. Paul goes looking for them and finds his necklace gift discarded on the floor. He doubles over with rage.
Meanwhile, Britney and shaggy guy have driven away, walking across a field into the sunset. At last - Britney gets a proper happy ending with the guy.
P.S. Happy 30th birthday, Brit!
