Sugababe Heidi shows her wild side in her leopard-print bikini in Miami

Sugababes singer Heidi Range took a walk on the wild side yesterday as she flaunted her curvy figure in a leopard-print bikini.

The Liverpudlian pop star, 25, soaked up some last minute rays as she enjoyed the last few hours of her Miami holiday before flying home to Britain.

Heidi and her older sister, make-up artist Hayley, 27, flew to Florida for a week in the sun in between Sugababes festival gigs and studio time.

After showing off a variety of different bikinis throughout the week, Heidi opted for a flamboyant leopard-print one for the last day of her vacation.

Choosing such a loud bikini demonstrated the singer had gained in confidence as her tan deepened.

Earlier in the week, a less confident Heidi covered the bottom half of her body with a pink skirt as she joined Hayley on Miami's South Beach.

After the pair started being photographed by paparazzi on the beach, they quickly summoned security who escorted them back to the their five star hotel.

Heidi has previously admitted she hates being photographed on the beach because it highlights her insecurities.

After she was photographed on the beach holidaying with her TV presenter boyfriend Dave Berry, Heidi admitted the sight of paparazzi made her want to cover up.

She said: 'I'm just the same as anyone else, I don't love my figure or anything, so it's not nice when the press pick up on things.

'There was a picture in the paper of me where I was leaning and they had a close-up of my nipples. Everyone gets that when they lean over on the side!

I went on holiday to Mexico and wouldn't walk around without my sarong on in case they caught a dodgy picture of my a**e.'

Next week, Heidi is set to reunite with her bandmates Amelle Berrabah and Keisha Buchanan for a performance at a charity concert in Dagenham, Essex next week.

The trio are set to resume recording on their sixth studio album, due for release later this year.

Heidi is also looking forward to decorating her new house after recently moving in with long-term love Dave.
