Britney Spears' new album reportedly features an ode to her paparazzo ex-boyfriend Adnan Ghalib.

The couple ended its controversial and tumultuous romance earlier this year, but sources close to the single pop princess claim she is still "crazy about" the British photographer, and sends a message to him in the lyrics to Mmm Papi, which features on her comeback Lp Circus.

Spears sings, "You love it when I'm freaking out/Things get rough and there's no doubt/You will always be there for me."

Spears' songwriting partner Nicole Morier tells Us Weekly magazine, "It's about someone I'm sure you can guess."

The magazine's source adds, "It's a gift to him (Ghalib). She is crazy for him."
