There's no doubt about it, Cheryl Tweedy is back at the top of her game. With a sell-out reunion tour for Girls Aloud, where fans are going wild for her, there's no stopping the singer. But as her 41st birthday approaches on 30 June, sources are saying that she feels like something is missing - another baby.

With four BRIT Award nominations and seven million album sales in the UK under her belt, Cheryl has been making waves in the showbiz world ever since she shot to fame on Popstars: The Rivals in 2002 and later as a judge on The X Factor. But the one thing that's made her life feel truly complete is being a mum.

In fact, the 40-year-old - who shares son Bear, seven, with former One Direction star Liam Payne, 30 - once famously said, "I know that is what I was put on earth to do-to be a mother."

Now, according to our source, it's a mix of nostalgia and broodiness that has led the Fight For This Love singer - who is currently touring with bandmates Kimberley Walsh, Nadine Coyle and Nicola Roberts - to believe it's now or never to have a sibling for her only son.
