Melanie Brown hard "Green Bikini" body on Sydney Harbour Bridge

She became the face of one of the world's leading weight loss companies last autumn as she made a bid to shift the pounds after her third child.

And although Mel B has worked hard to drop the post-pregnancy weight, the results of which are all too clear to see, it might be that she has taken it a bit too far.

The former Spice Girl was snapped on board a yacht with her husband Stephen Belafonte in a green patterned bikini which showed off her toned physique, the result of her programme with Jenny Craig and a tough exercise regime.

But despite the 37-year-old's impressive physique and rock hard abdomen, she had lost her famous curves around her hips and bottom and instead looked very boyish.

Thankfully she had not lost any around her bust and still boasts an ample bosom, which struggled to be contained in the bikini top.

Now permanently living Down Under, Mel joined the judging panel of the Australian version of the show alongside Ronan Keating last autumn.

But she said she was delighted to heading home and added: 'I’m so, so, so excited to be a guest judge in Manchester. Being a northern girl, I believe there’s lots of amazing talent in the north of England. I am coming to find the winner.
