"I believe Rob's going to be an amazing dad," Scott told E! News at his American Psycho Halloween party this weekend at the 1OAK Nightclub at Mirage Resort & Casino in Las Vegas.
Scott, who has three children with Kourtney Kardashian, isn't giving his longtime pal "strict advice on anything" when it comes to parenthood. "I think it's just something you need to figure out within time," he said.
Rob's spent a lot of time with his nieces and nephews as well as with fiancée Blac Chyna's 4-year-old son, King Cairo. "He's got one of the biggest hearts I've ever seen," Scott told E! News this past summer. "He's just an amazing guy and I'm so happy for him."
There's a lot Rob will learn from experience, but Scott said he's happy to be there one "kind of showing him the ropes of what it's going to be like to be a new dad."
Scott is looking to Rob and Chyna's little girl growing up alongside Reign, Penelope and Mason, too. "We're all such a close-knit family that all of our kids are more like brother and sister and not just cousins," he told E! News. "It's bigger than 'just cousins.'"
Watch the clips above to hear more from Scott on family, Rob as a dad and why "life is better" this year than the last.
