*Usher is looking to score Pippa Middleton as the face – or derriere – of his upcoming line of underwear.

The singer, 32, is releasing his first lingerie line later this summer and hopes that Duchess Katherine’s little sister will sign on for the ad campaign.

“I don’t think there’s a more beautiful, more stunning, more talked-about woman in the world at the moment,” Usher says of Middleton, 27. “I’m going to be approaching her in the next few weeks and setting up a meeting this summer.”

Usher says hiring the headline-making Brit is also a smart business move.

“The great thing about her is that she would be a global brand. Everybody knows her now, she would be perfect,” he tells Britain’s Look magazine. “I am sure everybody is trying to sign her up and she won’t be cheap, but she has the looks and the popularity to really establish a new product.”
