It’s on! Kourtney Kardashian’s on-again, off-again fling, Luka Sabbat, was spotted at Mason and Reign’s birthday party on Dec. 15, and woah, things are clearly heating up between the two stars.

Not only were Kourt’s sons having a blast, but her rumored boyfriend looked like he was having the best time too. The mom of three shared an Instagram Story of Luka and Mason hitting piñatas together. How cute! Of course, in true Kardashian fashion, the party was over the top with large TV screens, where kids could play video games, and a food buffet that included treats like cake and candy.

On Nov. 26, the KUWTK star was spotted smiling for the cameras as she was leaving Luka’s 21stbirthday party. It looks like the rumored couple is still going strong, despite their 18-year age difference.

However, there was one crucial person who was missing from the party: Scott Disick. The father of three didn’t forget about his sons’ special day, as he wished them a happy birthday via Instagram on Dec. 14. He wrote, “Happy birthday my loves!” So, where was the Lord? Well, he was with his girlfriend, Sofia Richie, in Saudi Arabia.

The duo shared many snaps of their trip abroad and it looked like they had a blast. They rode ATVs with singer, Miguel, and his wife, Nazanin Pimentel, and of course, both looked trendy AF during their time in the desert.

While it may seem like Sofia was not invited to the party, sources told Life & Style exclusively that that is far from the truth. “Kourtney is not icing Sophia out of the party she is having. The two of them are cool for the most part. If Mason and Reign love Sofia, then she is welcome to celebrate [their] birthday with them.”

Hmm, maybe Scott and Sofia didn’t want to be around Kourtney’s new beau? Whatever the reason, we’ll just have to wait and see if Luka is at the next Kardashian event.
