Britney Spears, Cameron Diaz, Scarlett Johansson, Jessica Pippa Middleton next?

Justin Timberlake has amorous feelings for Duchess Kate's sexy, scene-stealing little sister, the In Time star admits to Esquire's UK edition.

"Us American males are big fans of Pippa," Timberlake, 30, gushes to the British mag (excerpted by the Daily Mail) of Pippa, 27.

And Pippa's not the only Middleton beauty Timberlake loves. "We like the Middletons very much," he adds, alluding to Prince William's bride, 29. "I'm going to sound like a sleazeball. I'm going to stop right there!"

Alas, both Timberlake and the world's most famous Maid of Honor are spoken for. Timberlake and longtime love Jessica Biel resumed their on-and-off romance of four-plus years over the summer following a March split -- a breakup caused in part by his infidelity.

Middleton, meanwhile, reunited with beau Alex Loudon after a brief break.
