Kourtney Kardashian Has Dinner Date with New Man ... But Disick On the Brain

Kourtney Kardashian did dinner with a new man Sunday night -- in a very single mom kinda way -- and instead of romance ... Scott Disick was likely the main topic of conversation.

Kourtney was at Toscanova in Calabasas with two of her kids, Mason and Penelope, and the apparent suitor, whose name is Chris Reda. He's a good friend of Scott's, who's visited him in rehab recently ... according to our sources.

So there's a good chance he was just giving Kourtney an update.

Ultimately, Kourtney's recent night out in WeHo with Justin Bieber was probably more romantic than dinner with Chris.
