Jon Gosselin: It's Always Friday!! Now That I Work There

Jon Gosselin has gone from starring on a TV show with a brood of 8 to slinging food for a party of 8 ... at T.G.I. Friday's.

Jon's been working at the Lancaster, PA franchise for a few months, prepping and cooking family fare. The pic was taken at the restaurant when he started working there a month or so ago.

We're told JG even had to go through chef boot camp.

Friday's is giving Jon a chance to spread his chicken wings ... when he's not cooking, he gets to DJ once a month. It is his true passion, after all.
