The One Direction star revealed to KIIS FM that he had recorded his baby boy's heartbeat while he was still inside Cheryl’s womb.
"I made it into, like, a drum beat,” he explained. “It’s super cool. We haven’t really fit it with any song yet but, I mean, there’s a chance it.”
Both Beyoncé and Jay Z featured Blue Ivy on their respective tracks, Blue and Glory, the latter earning her the record being the youngest person to ever get a Billboard chart position.
Liam is gearing up to release his debut solo album, but first he's promoting his first solo single Strip That Down.
The song was written by Ed Sheeran and features US rap group Migos and will be premiered on Nick Grimshaw's Breakfast Show on BBC Radio 1.
Cheryl is also reportedly getting back in the studio in order to launch a music career in 2018.
The Fight For This Love singer – who welcomed Bear with Liam in March – is said to have been locked in top secret meetings planning her big comeback which will include a new sound.
The last time Cheryl, 33, released new music was three years ago and the pressure to get it right is on.
A source said: "Cheryl met with her label to discuss ideas for songs and to plan a new sound.
"It went really well and she is going to be meeting with producers next month before she heads into the studio for some early sessions," they added to The Mirror.
