When Rob Kardashian becomes a first-time parent in the imminent future, he won’t be getting any advice from Scott Disick — so says the lord himself.

“You learn as you go,” Disick told Us Weekly at 1 OAK’s Halloween bash in Las Vegas Saturday, October 29, while chatting about Kardashian’s baby-to-be with fiancée Blac Chyna. “There is no real advice you can give anybody and if somebody says there is, they’re lying.”

The 33-year-old, who’s the dad of Mason, 6, Penelope, 4, and Reign, 22 months, with ex-girlfriend Kourtney Kardashian, added: “It’s not easy. Kids don’t come with a rule book. You gotta figure it out yourself.”

That said, Disick doesn’t doubt Kardashian’s parental abilities for a minute.

“I think he’s going to be a great dad,” the Keeping Up With the Kardashians star told Us.

The Arthur George sock designer, who is expecting a baby girl with Chyna next month, has always wanted to be a father. As documented on the couple’s reality show Rob & Chyna, Kardashian revealed he was attracted to the makeup artist thanks to her bond with King Cairo, her 4-year-old son with her ex-fiancé, Tyga.

“I fell in love with her immediately because of how great of a mom she is and now I’m looking forward to starting a family with her," he gushed on the E! show.

And despite their tumultuous relationship, the pair seem to currently be on track. For Halloween, both King Cairo and Chyna jokingly dressed as Kardashian, complete with their own respective Los Angeles Dodgers hats.
