Rochelle Wiseman has revealed her glee at being an "auntie" - but admitted she's not ready for motherhood yet.
The Saturdays singer, who is engaged to JLS singer Marvin Humes, can't wait for bandmate Una Healy to give birth in March.
"I am most looking forward to Una having a baby. She's due on my birthday!" she said.
"I really hope she pops out on my birthday, I'd be chuffed. It's the first Saturdays baby! We can't wait. It's a girl. We're all going to be aunties."
The 22-year-old continued: "It's got me really excited to be an auntie. Don't get me wrong, one day I'll have kids but I'm not ready for that yet. I'm happy with my life.
"I think Una will be a great mum. I love kids, don't get me wrong, but just not for myself - yet," she added.
Rochelle and her bandmates will be performing at Asda's Tickled Pink fundraising concert alongside Alexandra Burke, Little Mix, Chipmunk and Dionne Bromfield, which takes place at the O2 Shepherd's Bush Empire tonight (January 12).
"Alexandra asked us to perform. She texted me and was like, 'I'm doing a gig for Tickled Pink, I'm really excited about it and I really want you girls to be involved'," the singer revealed.
"It's a great cause. We're excited to be there and it's amazing because 100% of the ticket sales go to Tickled Pink and that usually doesn't happen. So everyone's there for a good reason."
