It's a play date made in reality TV heaven: Hank Baskett IV and Mason Dash Disick!

At Tuesday's Hollywood premiere of A Nightmare on Elm Street, Kendra Baskett told which Hollywood baby she'd like her 4-month-old son Hank to hang out with: "Kourtney's! Of course! Baby Mason," she chirped of Kourtney Kardashian's boy Mason, born within days of Hank last December. (Mason's dad is Kourtney's boyfriend Scott Disick.)

Hank Jr. (dad is football star Hank Baskett) is doing great, the E! star cooed, but could use some baby company.

Kendra, 24, explained: "He's starting to lift his head and really look around...He's so smart. He mimics. He's starting to notice the dogs; he's like 'what are those?' I really want to start to find other babies he can be around. I don't want him thinking that he's a dog."

Motherhood has tamped down Kendra's adventurous side just a bit: she and husband Hank recently bailed "at the last second" on a shark diving expedition while on vacation in Hawaii.

"We looked at each other [and thought] 'is it worth it? What if we don't come back?' We [the baby] to always have parents! You know what I'm saying?"

The former Playmate added, "I'm not living for myself anymore, you know? I'm living for him. For the baby. I want to make sure every step of his way is with love and trust. It totally changes your life."
