The 33-year-old singer, who was a part of 'The Big Reunion: On Tour' along with other bandmates Liz McClarnon and Natasha Hamilton, said she doesn't even have alcohol these days, reported Daily star.
"I do not miss the drugs at all. I've done it, 100 lifetimes worth, I can't even handle a hangover anymore. On the Big Reunion tour, ask anyone, I was the first one in bed every single night. I think I went to one after show party which was the wrap party," Katona said.
Katona has four kids Molly, Lilly, Heidi and Maxwell. She is expecting her fifth child with fiance George Kay.
The singer is happy with the way her life has unfolded.
"I'm not going to sit here with regret, I definitely would not change anything. If I was to change something, I wouldn't be the person I am today. I wouldn't have the four amazing children I have. I wouldn't have met George," she said.
