Looks like Kylie Jenner and Tyga are definitely back ON!

The off-again-on-again couple spent Saturday night at a party with Scott. Oddly, they hid their faces from the cameras (hey, we know it's you, guys!) and kept their distance from each other. Tyga sported a Paul McCartney tee, supporting the aging Beatle after he was turned away at a post-Grammys party two weeks ago where Tyga was in attendance. The rapper had since come out in support of McCartney, saying he would have made sure Paul was granted access had he known security was blocking him.



Anywho ... the rest of the Kardashians kept busy this weekend, as well, Kourtney's been out and about with the kids -- shopping with mom Kris and taking the kids for an afternoon treat in Calabasas. Meanwhile, estranged baby daddy Scott Disick is up to his old tricks, partying with pals. We spotted him at The Nice Guy Friday night with his entourage and looking slightly worse for wear.



Khloe, the serious one, is keeping busy with Kocktails With Khloe tapings -- almost on the daily. Her guests in Saturday were so C-list we didn't even recognize them, but we DID recognizes those infamous curves on KhloKhlo as she left the studio in a sweatsuit and slides! It's been a while since we've seen her so dressed-down, but she always looks great!
