Liam Payne in a rush to complete album as Cheryl is expecting?

London: Singer Liam Payne is "having sleepless nights" as he tries to finish his debut solo album before his pregnant girlfriend Cheryl gives birth.

The 23-year-old former One Direction star and Cheryl, 33, are awaiting the arrival of their first child together, as the 'Parachute' songstress approaches her due date, reported OK! magazine.

Payne is said to be working tirelessly at the studio in order to ensure the album is completed in time for the arrival of the baby.

"Liam is in a real rush to get as much done before Cheryl goes into labour. He did as much work on his music in LA as he could but obviously he will be a father any day now so he's in London and has his phone on loud so he can rush to her side immediately if he has to," a source said.
