Nadine Coyle has said she does not miss her former Girls Aloud band mates - but hopes newlywed Cheryl Fernandez-Versini is "really happy".
The singer said she is still "in denial" about the group coming to an end.
The LA-based star, who is in London to sing in Michael Flatley's new show Lord Of The Dance: Dangerous Games, also hit back at critics of her Derry accent.
Asked if former bandmates Cheryl, Nicola Roberts, Kimberley Walsh and Sarah Harding will be coming to watch her perform at the Palladium, she said: "I don't think so."
Nadine, 29, did not say she would be meeting up with the women during her time in the capital, and when asked if she misses them, she said: "No."
She added: "I spend time with loads of people. I think it's just because maybe you're so busy that you just kind of get totally wrapped up in your own life."
Cheryl married French restaurateur Jean-Bernard Fernandez-Versini in a secret ceremony in July, but the couple were married for a week before it became public knowledge.
Asked about the marriage, Nadine said: "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."
She added: "So hopefully she's really happy."
Nadine, who has a baby girl called Anaiya with former American football player Jason Bell, reflected on her time in the band and said she "never wanted that to end".
She said: "I love... especially the Girls Aloud shows that we were able to do, so over the top, so huge... the songs that we had were so amazing so I thoroughly enjoyed all of the performances with Girls Aloud.
"I never wanted that to end... still don't. I am in denial."
The TV manufactured band came to an end after they reunited for a 12-date UK tour last year, after spending three years on solo projects.
Asked about her own wedding plans, Nadine remained coy. She said: "Wedding bliss for me? My sister's getting married so it's not all about me. It's all about my sister's wedding. And we're getting dresses and venues and caterers, so it's all about my sister now and then I'll think about getting married one of these days. Maybe."
Nadine, who has had her accent mocked in the past, said she does not get offended by it.
She said: "I can't decide which way I talk. I really, honestly can't. And it was funny, I was talking to an interviewer from Derry - there's so many of us around - and he said that when he came to London everybody thought he was American.
"I said 'I get that all the time. People think I'm from America'. When you're in Ireland you know it's a Derry accent. I was born and raised in Derry and I can't really change the way I talk."
She added: "My advice to people getting criticism over their accents would be tell people to mind their own business. Why are people working about their accents? Worry about your own accent. Never you worry about how other people talk."
Asked about motherhood, the singer said: "I find it great. I can't believe I didn't do it sooner. If it's not about Anaiya, it's not on my radar at the minute."
