Britney And Robin Thicke Sitting In A Tree

Britney’s said in past interviews she’d like to hook up with Robin Thicke… in the studio, but the two may have done more than just record a song together.

In Touch magazine claims Brit and Robin had a fling in 2003 “when Britney was at the top of her game and Robin was trying to get recognized,” a source reportedly told the magazine. “He was trying hard to develop a reputation as a hot, young singer, and (Britney) was the biggest thing in show business.”

So thaaat’s why Justin Timberlake hates Robin.

Thicke was on a break from his high-school sweetheart, Paula Patton, who he later married.

Britney listed Robin’s “The Evolution” as one of her favorite music videos back in 2008. She even snuck into one of his concerts at the House of Blues in LA that year.

A source tells GossipCop the story’s not true. Uh huh.

Sorry, Miley. Britney really has done it all first!
