Six months?! She sure kept that one on the down low, didn't she?!
Speaking to Daily Mail, Marvin revealed: "It's amazing, [Rochelle] is doing so well and she's a real trooper. She's nearly six months - she's only a week away from being six months."
"She looks great and we're so lucky we're having a second child," Marvin added. "We're really, really excited."
The Capital FM DJ also said that the couple won't be finding out the sex of their unborn bubba - they want to keep it as a surprise.
"We thought it would be nice to keep it a surprise," Marvin revealed. "We're going to wait and see."
Rochelle only went public with her pregnancy in mid-November, meaning she managed to keep her baby news a secret for several months after finding out she is expecting again.
She and Marvin announced they are expanding their brood via Instagram.
Marvin told fans: "Absolutely delighted to announce that Rochelle and I are extending our family! We're over the moon! Baby Humes no2 is on the way!" While Rochelle said: "Ten tiny fingers, ten tiny toes, but who are you? Nobody knows…."
Rochelle has since shared a baby scan photo with her fans on the social media app, and added the cute caption: "Santa isn't the only one coming to town...Baby Humes, due 2017."
She and Marvin are already parents to daughter Alaia Mai, three. Rochelle gave birth to Alaia in May 2013.
Her arrival came nearly a year after Rochelle and Marvin tied the knot at Blenheim Palace in July 2012.
