Rochelle Humes and the girls led the way in sending Frankie and husband Wayne a flurry of tweets last night after they revealed they are expecting a second baby together.
In a statement, Frankie said she and Wayne are "excited" about the pregnancy, however she added that she has been suffering from severe morning sickness - similar to that experienced by Kate Middleton.
As a result, Frankie has pulled out of the forthcoming 'Strictly Come Dancing Live Tour', which is due to kick off on 16 January.
After announcing their baby news, fellow Saturdays star and mum-of-one Rochelle was quick to congratulate her friend. She tweeted: "Big Congratulations to @FrankieTheSats and Wayne who have another #BabyBridge on the way."
Bandmate Una Foden, who is also pregnant with her second child, added: "Congratulations to @FrankieTheSats and Wayne who are expecting their 2nd baby later this year."
Mollie King, meanwhile, joked about the couple having a baby so soon after the birth of their son Parker - who arrived in the world in October 2013. She said: "Haven't you two got a TV @FrankieTheSats!! So so happy for you, Wayney and little Parker! xxx."
Vanessa White also sent her good wishes to the couple, adding: "So happy and excited for @FrankieTheSats and Wayne on expecting baby number 2!!! Xxx."
Frankie and Wayne tied-the-knot in front of family and friends in July last year and, for the past few months, she had been battling it out of the dance floor on Strictly Come Dancing.
Frankie made it to the final of the BBC One show and had been due to join the likes of Caroline Flack, Mark Wright and Alison Hammond on the official 'Strictly Live Tour'.
In her statement, however, Frankie told fans: "Although this is such an incredible time for us as a family, due to health reasons I am sadly unable to go on the Strictly tour as planned.
"I'm devastated that I'm missing out, as I loved Strictly so much and was so looking forward to joining everyone again in all those fabulous arenas.
"Thanks for the warm messages I've already received, they are really appreciated."
