The 'Voice' presenter - who is expecting her third child with husband Matt Willis - has developed an obsession with the calorific sweet treat and can't stop scoffing it down.

Speaking about her pregnancy, she told BANG Showbiz: "You can't make a cake out of just flour it takes a lot of things. I say cake because I eat a lot of it at the minute."

The brunette beauty will be just weeks away from her due date when 'The Voice' concludes in April and she's hoping her co-star Marvin Humes, who has daughter Alaia-Mai, two, with his wife Rochelle, will be able to take on most of the hard work when the competition hits the live shows.

She explained: "I will probably be relying heavily on Marv because I'll be about eight months by then.

"So, yeah, Marv is going to have the weight of two human beings on his back."

Meanwhile, Emma, 39, believes the forthcoming fifth series of 'The Voice' will be the most successful yet as the new coaches Boy George and Paloma Faith, who have replaced Sir Tom Jones and Rita Ora, work really well with returning judges Ricky Wilson and will.i.am.

SHe said: "Something has fallen into place, I don't know whether it's the new coaches or the subtle differences in the format.I think that George and Paloma have certainly made a difference, they have so much personality and so much charisma. Will seems to bounce off them brilliantly and Ricky has that relationship with Paloma and has done for years. I want more of them in the show."
