Once upon a time, Ryan Reynolds launched his latest show.

The Deadpool star, 46, recently revealed he's releasing a new series called Bedtime Stories with Ryan, and he gave a subtle shout-out to his fourth child with Blake Lively in the announcement. 

"The idea for a show made to help everyone fall asleep was born the same day as my fourth child," Ryan wrote in a June 15 Instagram post alongside the trailer. "I can't wait for you to watch Bedtime Stories, premiering June 20th on @MaximumEffort Channel on @fubotv."

While Ryan and Blake never formally announced the arrival of their new baby, the Gossip Girl alum—who revealed the pregnancy last September—posted a picture of herself sans baby bump in February. And since then, Ryan has noted the couple—who are also parents to daughters James, 8; Inez, 6, and Betty, 3—are enjoying life as a family of six.

"We're very excited," he said on a February episode of CNBC's Power Lunch. "Look, we wouldn't do this four times if we didn't love it."

Blake and Ryan have yet to reveal the name or sex of their newest family member. However, the Free Guy actor did tell followers more about his new program.

As the name suggests, the series features Ryan telling bedtime stories to, per a press release, help "sooth your mind and soul (and also his own)." 

"You know the best part about stories? You remember them. They stay with you," he said in the trailer. "And I want to tell you a bedtime story."

Bedtime Stories with Ryan will premiere on Maximum Effort Channel when the channel—which is a partnership between Fubo and Ryan's ad and content creation company—debuts June 20. 

So while you can't watch Ryan read a bedtime story just yet, you can read some of his and Blake's quotes on parenthood by scrolling on.

"I have seen Frozen with my daughters so, so many times and people don't know this, but if you play Frozen backwards, it's actually a shot for shot remake of The Exorcist," Reynolds joked on The Ellen DeGeneres Show in 2018.

On Dec. 15, 2016, Reynolds and Lively debuted their daughters James and Inez for the first time, at the actor's Hollywood Walk of Fame Ceremony (a common setting for notoriously private celebrities to introduce the world to their kids). During his speech, Reynolds said to his wife, "You make everything better—absolutely everything in my life better. You've given us two of the most incredible children that I could ever hope to have. You've made me the father of my dreams when I thought I only had fun uncle potential."

In August 2016, before the birth of the couple's second daughter, Reynolds told E! News, "There's nothing on earth more grounding than having a baby. It's the best thing that could ever happen to someone."

"It's tough when you get pooped on and barfed on, but having a baby is wonderful," the proud mama told NW Magazine in 2016. "Even when it's tough and I'm exhausted, I think, 'I am so fortunate.'"

During a visit to the Late Show with David Letterman in 2015, Reynolds gushed about his marriage and his daughter, but made sure viewers knew who was more important. "'I would take a bullet for you. I could never love anything as much as I love you.' I would say that to my wife. And the second I looked in that baby's eyes, I knew in that exact moment that if we were ever under attack, I would use my wife as a human shield to protect that baby."

In tradition with his dark sense of humor, Reynolds shared this little parenting joke with his Twitter followers in 2016: "Being a father is the single greatest feeling on earth. Not including those wonderful years I spent without a child, of course."

"I always do the dirty work," Reynolds said on NBC's Today show in 2016. "I'm happy to do the dirty work. So does she, but I'm always, I love getting up in the middle of the night, I'm fine with that, you know, all that stuff."

Fatherhood, he said, has been "amazing."

"I had one of those mornings, rare mornings, where my daughter just didn't want me to leave—and it was only because my wife was asleep," Reynolds said in 2016. "But it was like, you didn't want to go. You just like, it kills you."

"You know, what was really weird was, we were watching the Super Bowl and my daughter saw it and she totally recognized me. There was like 12 of me, which is just like, to her, was like 24 useless boobs," Reynolds said in 2016. "She was so not impressed. She was like, 'Eh, whatever.'"

"Damn it's hard letting your infant daughter go somewhere alone for the first time, I was a total mess dropping her off at Burning Man," Ryan joked to his Twitter followers in 2016.

"She's great, man. She's great," the proud papa gushed in 2015 before revealing whether the couple's then-only child James has started speaking. "We're getting a lot of sounds, nothing that sounds like discernible English at this point," he quipped, adding, "I'm mocking her a lot."

"@vancityreynolds Since the day our baby was born, I've felt so strongly in my heart that you were most likely the father," Lively wrote on Instagram in 2015. "#ILoveYouSoMuchItsSilly."

"Having a baby is just living in the constant unexpected," Lively said in 2016. "You never know when you're gonna get crapped on or when you're gonna get a big smile or when that smile immediately turns into hysterics. It might be like living with a drug addict. But you have a baby and you think, 'I can't imagine ever not having a baby,' because they grow up so quickly. I'd be an 80-year-old woman with a baby if I could."

 "It's the best," Lively said in 2015. "It's the thing that binds us all—family. We have very unique jobs for a living, but we all are a part of someone's family. It's a nice thing."

"On Father's Day, my daughter smiled at me," Reynolds tweeted in 2015. "It was all the gift I needed as I packed a bag and left for 6 years to write a book on parenting."

"There have been times where I woke up, literally had no idea I had been walking for five minutes," he told E! News while promoting his movie Woman in Gold in 2015.

"But you love it. You wake up in the middle of the night, you got a big stupid smile on your face. I was telling someone else that. Anything else that woke you up every 45 minutes, you'd kill it. But when it's a baby, it's the best thing that ever happened to you."

"One of the most common things in the world is making out, having a couple of drinks, and then doing it, and then having a baby. I was perfectly sober for this one though. I gotta say," Reynolds joked in 2016.

"It's amazing. I just always marvel how common it is and yet how profound it is. And I always laugh because you know celebrities you always cringe when they talk about their kids. Like 'my child is the only one that has ever exited a womb out, ever.'"

"Well, a lot of people have done this, so you always want to temper it with a little of self-effacement. But I love it," Reynolds said in 2015 about then-only child James. "I truly worship that kid. It's terrible. She has me so far wrapped around her finger it's dumb. She says 'Dada' and I will walk through a cement wall to get to her."
