Tyler Perry says he hasn't gotten a chance to congratulate his friend, Janet Jackson, on being pregnant with her first child
, but he's "looking forward to it."
"She's just always been so extremely private and is laying low, and I just wish her all the best," Perry tells ET's Denny Directo. "I'm excited for her, because I know what that means."
Jackson announced her pregnancy news in May, just two weeks shy of her 50th birthday.
"I thought it was important that you be the first to know," Jackson said in a Twitter video. "My husband [Wissam Al Mana] and I are planning our family."
Perry welcomed his first child with partner Gelila Bekele in 2014, but the media mogul doesn't have too much parenting advice for Jackson.
"There's nothing people can tell you to prepare for it. It is what it is," Perry explains. "I think that is going to give her a sense of fulfillment that she's never had before."
Perry has some big news himself as next week will mark the release of his latest film, Tyler Perry's Boo! A Madea Halloween, in which his outspoken alter ego faces off against killer clowns and runaway zombies.
While Perry admits he "doesn't do" Halloween in real life, he reveals that he has Chris Rock to thank for the idea of the film.
"Lionsgate called after they saw Top Five, and in it, Chris Rock did this spoof called, Boo! A Madea Halloween, and they called me up going, 'You got to do that movie!'" Perry recalls. "When I came up with this concept, I was actually watching YouTube videos of people getting pranked, so I came up with the concept and I thought, 'This is going to work.'"
While Rock won't be getting any producing credits, Perry says he will give the comedian a "nice handshake" and a "thank you very much."
Boo! A Madea Halloween opens Oct. 21.
