Listen to Britney Spears on iHeartRadio

(Yahoo!) - Oops, she's done it again. Britney Spears is making headlines for kissing a new boy toy. Apparently, she was so excited by the kiss, she even posted a pic of the liplock on Facebook.

It happened on Tuesday in the Southern California desert, but her boyfriend, David Lucado, shouldn't freak. The "Toxic" singer was locking lips with the grunge-looking hunk for a new video clip for "Perfume," a track from her eighth album, Britney Jean album, which is due Dec. 3.

Britney herself was dressed down for the shoot, forgoing her usual glammed-up, sex-kitten clothing for jeans, boots and a white tank top shear enough to show her matching white bra. When things cooled down in the evening, both Spears and her mystery man donned leather jackets, according to US Weekly.

The clip is being directed by Joseph Kahn, who lensed previous Brit vids for "Stronger" and "Toxic." Britney tweeted about the collaboration:

If the mystery man looks younger than the 31-year-old Spears, it's because he is. He's been identified as 28-year-old Norwegian model Alexander Kjellevik.

Spears has said that the song "Perfume" and the rest of the album is deeply personal. The song includes the lyrics, "And while wait I put on my perfume, yeah I want it all over you, I gotta mark my territory." That might make you think that Britney's like a rabid dog in heat, but have no fear, she's doing it all for the fans, she said in a tweet:
