Muscular Spice! Mel B shows off a very taut and toned physique as she enjoys a romantic yacht ride with husband Stephen

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.

In what appeared to be posed-for pictures, Mel and Stephen enjoyed a romantic sail around Sydney Harbour as the sun set behind them.
The couple were no doubt making the most of their time together before jetting off the to UK where Mel will be a guest judge for the X Factor and the Manchester auditions.

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.

Mel B's adorable daughter Angel gets to grips with her mother's pregnancy curves

It can be a confusing time for a child when their mother announces they are expecting another baby.

But Mel B's four-year-old daughter Angel Iris appeared to be entirely embracing the thought of welcoming a sibling into her family as she enjoyed a day out with Mel B and her mother's husband Stephen Belafonte.

The adorable tot was seen kissing her mother's burgeoning baby bump and at one point appeared to be talking to her unborn brother or sister as the former Spice Girls star and Belafonte looked on with delight.

And it wasn't only Angel who appeared thrilled with 35-year-old Mel's pregnancy curves, as Belafonte also struggled to keep his hands off his stunning wife, who displayed her figure in a tiny white bikini.

As well as showering Mel, who is five months pregnant, with kisses and playfully grabbing her bottom, Belafonte treated his spouse to a relaxing foot massage as they sat by the swimming pool while Angel played in the water.

But while everyone else seems to be enjoying Mel's ever-growing figure, Scary Spice has been tweeting fans she is amazed at how quickly her body is changing.

After commenting last week that her bump had 'doubled in size overnight', Mel wrote on her Twitter page today: 'Hell yizzels!!! My bump and my ass have towns named after them now!! Hahaha.'

Mel revealed earlier this year that she is expecting her third child - her first with film producer Belafonte.

Making the announcement, Mel told Hello! magazine: 'We’re really excited. We wouldn’t have planned and waited for four years to have a baby if we weren’t really excited about it and ready for it, even though you can never really be truly ready.'

Meanwhile, as well as using Twitter to update her fans throughout her pregnancy, Mel has also been using the social networking site to end a two-year feud with her family.

The singer is thought to have cut off all ties with her sister Danielle, mum Andrea and dad Martin in 2009 because they disapproved of her marriage to second husband Belafonte.
