There's no way his baby mama is cool with this!

Scott Disick had girlfriend Sofia Richie join him and his kids Mason and Penelope for dinner in Malibu over the weekend, and we're pretty sure this is still a big no-no where Kourtney Kardashian is concerned! The eldest K sister has introduced her boyfriend Younes Bendjima to their brood, but she allegedly doesn't want Scott's teen model lady love anywhere around them. It's a bit of a double standard, but we understand!

The former partners are said to be "not in the best place" as they attempt to co-parent and carry on new relationships, so it's no surprise The Lord isn't taking marching orders from Kourt any longer.

A source tells X17:
    "Scott has told Kourtney he's had enough with her hypocritical behavior. He's not going to have her dictating when Sofia is allowed to be around any longer, and it's ruffling her feathers. Kourtney just thinks it's totally inappropriate for a 19-year-old to be playing stepmom to her children, but there's really nothing she can do at this point. It's her worst nightmare, but she never likes people to think anything gets under her skin, so she's playing it cool for the time being."

This would make us furious!
