Marvin Humes reveals wife Rochelle is SIX MONTHS pregnant (and they won't find out the sex of their baby)

The stars took to Instagram to reveal the happy news

It was just one week ago that Rochelle and Marvin Humes announced the lovely news that they're expecting their second baby.

But it seems Saturdays singer Rochelle is a lot further along than first thought, after hubby Marvin revealed she's actually only a week away from being six months pregnant!

Marvin, 31, was appearing at Global's Make Some Noise charity bash when he let slip some exciting details about their new arrival to Mail Online.

Gushing about his wife of four years, the radio presenter said: 'It's amazing. She's 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's still working loads and even with Alaia-Mai she's amazing. She looks great and we're so lucky we're having a second child and we're really really excited.'

However, unlike many parents-to-be, the celeb pair have decided to keep the sex of their baby a surprise until the birth. 'We don't know the gender. We found out with Alaia, our second child we thought it would be nice to keep it a surprise.

'We're going to wait and see, we don't know yet,' Marvin added.

Rochelle originally took to Instagram to reveal the happy news to her fans, sharing a black and white picture of herself cradling her growing bump.

'Ten tiny fingers, ten tiny toes, but who are you? Nobody knows...💗💙' she wrote alongside the snap.

Marvin also shared his joy at the new arrival with a series of similar pictures, writing: 'Absolutely delighted to announce that we're extending our family! Rochelle and I are over the moon! Baby Humes no2 is on the way!!! ❤️'

Rochelle, 27, and Marvin, 31, started dating in March 2010 and tied the knot in a romantic ceremony at Blenhiem Palace two years later. The pair are already parents to daughter Alaia-Mai, three.

Speaking previously about the possibility of having more children, Marvin said he was keen to expand their brood.

'I want another one, I really do. If I had my way, we'd have one every year,' he said to HELLO! magazine.

'But obviously it's not just up to me and Rochelle's taking a bit of persuading. I tell her she will have it easier with the second pregnancy but so far she's not buying it.'

Rochelle agreed that she'd had a tough pregnancy with Alaia: 'I felt ropey from the start and it didn't get any better. They thought I was having twins at first because my hormone level was so strong.'

'Marvin was excited about that prospect, but I was freaking out, going, "Two? It's my first time, I'm not sure I can cope."'

'Thankfully, it was just Alaia but I did struggle. I felt sick, tired, huge, weepy and unattractive.'

She later said that they'd love to add to their family, but added that she was in no hurry at the time.

She explained to MailOnline in 2015: 'I'm really enjoying my little girl's age, she's becoming a real person now.'

'I've got used to our system so I'm going to enjoy that for a bit longer. At the moment I've only really got time for Marvin and Alaia. In due course, when I'm ready to take some time off, then I will.'
