Speaking at the glamorous bash held at Supernova in central London, he spoke sweetly of his wife, revealing: '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 (now 3) was born so she's amazing. She looks great and we're so lucky we're having a second child and we're really really excited. 

'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.'

Last week Rochelle shared a stunning black and white snap as she cradled her rounded belly, with the caption: 'Ten tiny fingers, ten tiny toes, but who are you? Nobody knows...', while Marvin shared a collage of images of his stunning wife.

Rochelle and Marvin began dating in 2010 before marrying in 2012 in an idyllic ceremony at Blenheim Palace before welcoming their daughter in 2013.

A representative for the couple confirmed the news to MailOnline, saying: 'They are both over the moon', before they began their Instagram spree.

Elsewhere Marvin shared a collage of images from the same shoot, while adding the gushing caption: 'Absolutely delighted to announce that we're extending our family! Rochelle and I are over the moon! Baby Humes no2 is on the way!!!' 

'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' Marvin said at the charity bash

Just one week prior to the announcement Rochelle confessed that she feels pressure for another child from her little girl, who is desperate for a brother or sister to play with.

'I’m feeling it from Alaia, for sure! She’s already quizzing me and saying that her friends all have brothers or sisters,' the singer-turned-TV presenter told The Sun's Fabulous magazine.

Rochelle added: 'At the minute I feel so blessed and happy with the way everything is that I’d never put pressure on that, but definitely in the future.' 

Marvin was at the star-studded event which raises money for Global’s Make Some Noise, the charity set up by Global, the media and entertainment group, to help disadvantaged youngsters across the UK.

It's the 3rd annual gala event for the worthwhile cause which aims to give a voice to small charities that struggle to be heard.

Global's Make Some Noise is a national grant-giving charity that helps change young lives. Created in 2014, it supports projects that help disadvantaged youngsters by raising money and, crucially, giving them a platform to tell their story to millions of people.
