He may be divorced from Britney Spears, but Kevin Federline had his eyes on a new model with the same namesake.

The wannabe rapper, who has custody of his children with the pop wreck, was partying at an LA hotspot earlier this week when someone caught his attention.

A source tells Page Six that K-Fed was "staring at Brittny Gastineau while she was waiting in line for the bathroom.

"(He) wouldn't stop checking her out, up and down, but Brittny was not interested,” adds the source.

He’d have more chance with his ex-wife than a new Brit.
