Britney Spears' ex-husband Kevin Federline was spotted lugging his sizeable heft (and girlfriend Victoria Prince) around Vancouver on Monday.

After a failed attempt at becoming a rap superstar, K-Fed has changed tack and decided to top up his alimony payments by pursuing a career in acting.

The former backing dancer told us he was about to begin filming in the city, but didn't give any more details.

Could the Fedster have bagged a top secret cameo role in Twilight sequel New Moon? (Answer: No)
