While singer Frankie, 25, and 34-year-old Wayne are obviously thrilled with the news of a baby brother or sister for son Parker, it means she has had to drop some work commitments.
One of which is the Strictly Come Dancing tour.
But mum-of-two Rachel, who has also taken part in the show before, is more than happy to fill her space.
Rachel said: “I’m really happy for Frankie and Wayne – it’s great news to start the New Year with! I know she’s disappointed not to be doing the tour – I was supporting Team Frankie during the show and she was fantastic, but I’m happy to be able to step in for her.
“It’s not secret that I loved my time on Strictly andy that I’m a big fan of the dances so I’m excited to be back and to get my dancing shoes on again.
"Today, I’m straight into rehearsals learning the routines and meeting the guys and next week we’ll be on tour meeting the guys and next week we’ll be on tour seeing fans across the country - I can’t wait!”
Rachel came runner-up on the show in 2008, featured during the 2009 tour and last year appeared on the Christmas special – so she’s more than qualified to take over from Frankie!
It’s been a busy few months for the 36-year-old; S Club 7 reformed for Children In Need in November and are now planning a reunion tour, and she was recently announced as a judge on The Voice of Ireland, alongside Frankie’s bandmate Una Foden, 33.
