Say what you will about Scott Disick, one thing is for sure: He is definitely a doting dad to son Mason, 2, and newborn daughter Penelope, 3 months.

Welcoming his family's new arrival in July with girlfriend of five years Kourtney Kardashian, 33, Disick, 29, tells Us Weekly his outlook on fatherhood has evolved since his little girl came into the mix.

"My son is my world and my daughter is my new world. So, it all combines," Disick told Us when hosting a party at Chateau nightclub at the Paris Hotel in Las Vegas Saturday. "It's pretty unbelievable starting another chapter in your life. It's a lot better than not having children."

Having baby Penelope at home has brought Disick and Kardashian -- currently filming her E! spinoff Kourtney & Kim Take Miami in Florida -- even closer together. In fact, tabloid rumors of a split couldn't be further from the truth.

"They are better than ever," Kourtney's sister, Kim Kardashian, tells Us. "I feel bad Scott gets such a bad rap. Good thing they're too busy being parents to pay attention to nonsense!"

Agreed second-time mom Kourtney: "We're good right now with how things are. We're just trying to figure out our new life with two kids."
