The 'I Don't Care' hitmaker set tongues wagging earlier this week when she stepped out at a charity event with a burgeoning baby bump and, although her due date is not yet known, it's believed the little one is expected around the same time the One Direction hunk is scheduled to jet across the pond.

A source told The Sun newspaper: "Liam is doing what he can to make sure he spends as much time as possible with Cheryl before and after the birth, but some commitments can't be changed. Luckily Cheryl has an incredibly supportive family, who will rally round if they are needed.

"They will also be helping her and Liam after the birth, as Cheryl is saying she doesn't want to get a nanny."

It's believed the 23-year-old singer has been told by his record label to spend a few months early next year in California so he can finish his debut solo LP in the studio before the summer.

His friend Calum Scott recently admitted to BANG Showbiz that Liam already has a "few amazing songs" ready to go.

He said: "I was in the studio with Liam the other day. I heard a few of his songs. They are sounding amazing. I'd love to do something with him."

Cheryl, 33 - who has been married twice to Ashley Cole and Jean-Bernard Fernandez-Versini - and Liam began dating back in February but first met when the hunk auditioned for 'The X Factor' in 2010 when he was just 16 and she was a judge on the TV talent show, the series which created 1D and set the boy band on the path to global pop superstardom.

This will be the second One Direction baby following Liam's bandmate Louis Tomlinson having son Freddie with Los Angeles-based stylist Briana Jungwirth in January.
