Following the birth of her first child, daughter Anaiya with long-term partner Jason Bell, Nadine is back to work and singing in Michael Flatley's show Lord of the Dance: Dangerous Games.
Although they spent 10 years in the same band, Nadine is quite certain Chezza and co. will not be going to see her perform in her new role.

She told a UK radio station: "I spend time with loads of people. I think it's just because maybe you're so busy that you just kind of get to ally wrapped up in your own life."
She might be confident she won't be bumping into her during her visit to London, but Nadine does wish 30-year-old Cheryl all the best in her new marriage to Jean-Bernard.

Nadine continued: "I sent her a wee message to say congratulations… I mean it was a whole whirlwind thing so she must have been just having a ball of a time. So hopefully she's really happy."
Speaking of Girls Aloud, Nadine revealed she really didn't want things to end following their 10th anniversary album and tour.
She added: "I never wanted it to end… still don't. I am in denial."
