Britney Spears: Pauly D, I Love Your Hair!

Britney Spears drops by Barnes & Noble to buy a few CDs with her bodyguard on Monday (November 1) in Calabasas, Calif.

The 28-year-old pop princess picked up four discs, including Lily Allen‘s 2009 album It’s Not Me, It’s You.

Brit recently met Jersey Shore star Pauly D in the studio, prompting him to tweet that his “life is complete!!!”

“Awww nice to meet you too @DJPaulyD. Love the hair,” she replied back to him.

Over the weekend, Brit‘s adorable sons, Sean Preston and Jayden James, went trick or treating with their dad Kevin Federline.
