Nadine Coyle is "very excited" about Cheryl becoming a mother

She told OK! magazine: "I’m so, so excited. It’s the most exciting time, scary but wonderful ... I haven’t seen her in a long time, I really, really haven’t. But I’m very, very happy for her and very, very excited for her."

Meanwhile, Liam previously admitted Cheryl has always been his "dream girl".

He said: "This is the thing. In a non-cliché way, it's weird waking up every day and literally living out your dream. You wake up in the most beautiful places.

"Obviously I have the most ­beautiful girlfriend in the world and she's absolutely amazing. She's been my dream girl since I was younger. She's so ace."

Whilst Liam didn't mention Cheryl's pregnancy, the former One Direction star admitted it is a very "precious" time for the couple.

He gushed: "We're super happy. It's a very personal, precious time for us ...

"She is a wonderful, wonderful person and it's amazing to have someone who can relate to so much of things -- someone who's taken greater steps than me.

"Her solo career was ­amazing. She's been in the ­industry for 14 years now. She fully supports me."

And Cheryl and Liam are gearing up for the arrival of their little bundle of joy.

A source said last month: "The rumour mill has been rife that the birth is imminent and there have even been claims she's in labour already but that's not the case at all.

"She's still a little way off and has been enjoying the build-up as well as focusing on her charity announcement which is a really big deal for her."
