Kerry Katona is pregnant with her fifth child.

The Atomic Kitten singer - who already has daughters Molly, 11, and Lilly Sue, 10, by her first husband Brian McFadden, and Heidi, six, and five-year-old son Max with her second spouse Mark Croft - is expecting her first baby with her fiancé George Kay and is over the moon with the news.

Speaking to Alan Titchmarsh on his chat show, which airs today, she said: ''We've just found out we're having a baby - I'm three months pregnant. I have food and a baby in my belly, the best friends in the world, a great job and I'm a very lucky girl. I'm very grateful.''

The 33-year-old star is also preparing to walk down the aisle for the third time later this year when she weds childhood friend George after he popped the question in April at the top of Blackpool Tower, Blackpool, in Lancashire.

The bubbly blonde - who was declared bankrupt in 2008 - has been hit with a string of bad news since rising to fame, including being admitted to rehab for Bipolar Disorder and, most recently, dropped from payday loan Cash Lady after filing for bankruptcy for the second time.

However, the reality TV star is confident she is moving in the right direction in life and insists she's learnt from previous mistakes.
