The 27-year-old took to Instagram to share his happy news and simply captioned the photo “x”
The couple got married last month and Chloe tweeted an extremely sweet message saying: "I married the man of my dreams yesterday! Had the best day of my life!! I can now officially say I am Mrs Chloe Gill."
Bandmate Marvin Humes took to Twitter to offer his congratulations to the pair. He wrote: "So so so excited! @JBGill and @ChloeSGill are expecting a baby!!!!!!!!! Boom! Congrats guys!x"
Marvin’s wife The Saturdays’ singer Rochelle Humes also expressed her excitement at the happy news and tweeted: “"@ChloeSGill @JBGill You don't understand how excited Auntie Roch is...I nearly burst with excitement! Love you guys too much."”
No doubt Marvin and Rochelle, who are parents to Alaia-Mai, will be able to offer the couple plenty of advice.
Congratulations to JB and Chloe.
