The One Direction star has likened his partner - with whom he shares five-month-old son Bear - to ''superwoman'' and praised her for ''working hard'' to perfect her post-baby body.
Speaking to BANG Showbiz at the VOXI launch event on Thursday (31.08.17), Liam said: ''Cheryl's like superwoman. She's done so well and is so happy with herself. She's been working hard and if you do work hard, you get what you want.
''She had her rest time bonding with Bear at the start. She's incredible, a natural mom. We take a million pictures of Bear but we want him to be able to decide what he wants to share when he's older.''
And the 24-year-old singer feels really lucky to have such a close family and revealed Cheryl recently flew his family and friends out to Mallorca to celebrate his birthday with him.
Asked about his recent birthday, he added: ''We got away for a little holiday. Cheryl flew all my old friends out. And on my birthday, she flew out my parents and I haven't spent my birthday with them in years so it was great.
''We were in Mallorca and spent time with Bear who is getting so big. He's like a tiny Michelin man. He's got some lungs on him, gets that from both of us. We're both really excited about the future.''
