Kerry Katona has become a mum for the fifth time.
The former Atomic Kitten singer welcomed a daughter on Friday (April 4).
Her fiance George Kay shared the news on Twitter, saying: "@KerryKatona7 thank you for bringing my beautiful daughter into this world last night! You are both amazing xxxxxxxx."

Kerry, 33, didn't comment herself but retweeted George's message. The couple have not announced the name of their new arrival, but are thought to be naming the baby Jorgie, after her dad.
They had apparently picked out the name George earlier in the pregnancy when they thought Kerry was having a boy, but tweaked it when they discovered she was actually expecting a daughter.
In December, George was quoted as saying: "We're having problems picking a girl's name. Mind you, we might pick the same name for our little girl as we'd chosen for the boy as it's a unisex name."
Kerry's former bandmates are among those who have tweeted their congratulations, with Liz McClarnon writing: "Well I'm in love, baby Katona/Kay is perfect. I met her finally last night. Well done @KerryKatona7 & @mrgajkay xxxxxxxxxx."

Natasha Hamilton, who is expecting a baby with Ritchie Neville, tweeted: "And a huge congrats to @KerryKatona7 & @mrgsjkay on the arrival of their baby girl. Can't wait to get back to uk and get some cuddles xxx."
Kerry, 33, is already mum to Molly and Lilly Sue from her first marriage to Brian McFadden and Heidi and Maxwell from second husband Mark Croft.
