Kevin Federline may smoke, but he definitely wasn't the culprit when ex-wife Britney Spears abruptly halted her concert last night in Vancouver.

How do we know this?

Well, Mr. K-Fed was spotted getting his puff on right here in the Los Angeles area. Sean Preston and Jayden James' daddy was at what looked like dinner with volleyball player girlfriend Victoria Prince at a local T.G.I. Friday's when he stepped out of the eatery for a bit.

"He left the table to go chain-smoke outside," a fellow diner reports. "He was outside for, like, 20 minutes."

Looked like Ms. Prince may not have been too thrilled about Federline's disappearance.

Says the source, "He was talking to some other girls outside, and when he finally came back to the table, his girlfriend looked angry and they started to argue."

If they weren't arguing about K-Fed's new female friends, perhaps it was over...who should get the last buffalo wing?
