Kourtney Kardashian has got a new man! She dumped Younes Bendjima, 25, for apparently cheating on her and then went on to another male model and family friend Luka Sabbat, 21. Now she's traded him in for a fellow Hillsong follower and NON-famous dude David Dee Duron.

Kourt and Duron -- who's the oldest of KK's recent conquests at an elderly 26 years old! -- were spotted on a dinner date the other night at Nobu Malibu. The couple were beaming as they exited the restaurant -- Kourtney wearing a decidedly dressed-down nylon windbreaker and black PVC straight-leg pants and Duron in jeans.

Duron hails from Miami where he attends Hillsong sister church Vous and apparently he made it out to LA for some reason and hit up Hillsong, where he met Kourt. Despite the romantic look the two had in their eyes as they left dinner, a source tells People magazine, the two haven't "gone there" yet: "It’s just friendship now. They met through the church and they have a lot of mutual friends. But for now, it’s just a friendly relationship. He’s a lot younger than her, so there’s an age difference. He’s about 12 years younger than her. But he’s very mature. He’s a serious Christian and so is she, and there’s definitely some chemistry there. They could turn into something in the future, but it hasn’t happened yet."

When we spotted Kourtney at the dry cleaners yesterday, she was all puffed up in a grey puffer jacket and sweats, again -- when we saw her previously, with sis Kendall at a late-night cosmetic dermatology appointment in Beverly Hills, she was sporting a similar look. Perhaps dating a regular guy gives Kourtney some relief from having to look super-fashionable all the time. We don't mind the sweats/no makeup look on her and she certainly looks more comfortable!
