Nadine Coyle has urged Cheryl Cole to "join the baby club".
The Irish singer - who has five-month-old daughter Anaíya with fiancé Jason Bell - congratulated her former Girls Aloud bandmate on her shock marriage to Jean-Bernard Fernandez-Versini and advised her to start a family as soon as possible.
She tweeted: "Aww @CherylOfficial you must be having an amazing time. I am so happy for you! Good luck with everything. Come join the baby club. Best ever (sic)"
Cheryl replied with a string of emoticon faces blowing kisses.
Meanwhile, following claims from her new husband's friend Curtis Jones that the club owner is a womaniser who can't be tamed, the 'Crazy, Stupid Love' hitmaker has issued a tongue-in-cheek response.
She posted a black and white Instagram picture of herself smoking with a quote printed over it which read: "I hear you're a player. Nice to meet you. I'm the coach."
Cheryl - who announced earlier this week she had married Jean-Bernard last week after two months of dating - also found the time to thank some of her former 'X Factor' mentees for their messages of support.
Rebecca Ferguson - who is pregnant with her third child - said: "it's nice to see you have found happiness and peace congratulations x"
Cheryl replied: "thank you babe. I hope everything is going well in your pregnancy"
And she offered a simple "thank you" to Cher Lloyd, who had said: "Congratulations!!! Wishing you both all the best!!!(sic)"
