Former "Jon & Kate Plus 8" star Jon Gosselin's family has some new additions ... two turntables and a microphone.
Gosselin tells TMZ he's ready to get the party started as a full-time DJ and go the route of Paris Hilton -- who's made beaucoup bucks spinning -- but he know he's gotta build his skills first.
He says he got hooked back in the '90s ... then a few years ago tagged along with an ex who's in the biz and got an itchin' for scratchin'. Now he's learning the ropes with 30-year vet, DJ Koolie.
Gosselin's been gigging on the reg, but not to pay child support ... he reportedly dodged that bullet when Kate waived her right to money in return for Jon allowing her to put the kids back on TV.
