Lewis Hamilton's Pussycat Doll sets pulses racing as she steps out in a skin-tight PVC dress

As one of five sexy singers in girl group The Pussycat Dolls, Nicole Scherzinger has found the perfect way to become the centre of attention.

Over the last few weeks, it seems Lewis Hamilton's girlfriend is being influenced by dominatrix fashion as she has been increasingly seen wearing PVC.

After pouring herself into a stunning grey PVC dress at the Vodafone Live Music Awards in London last month, the 30-year-old pop star opted for another rubber ensemble for her gig in Sydney today.

Dressed in a skin-tigh black dress with a peep-hole top section, it was clear to see what first attracted racing ace Lewis to the American beauty.

The unforgiving fabric clung to Nicole's amazing curves as she wiggled down the green carpet ahead of Tuesday's concert at the Royal Opera House.

Unsurprisingly, Nicole's restrictive outfit was just for the photocall - but her penchant for PVC continued as she opted for a pair of trousers in the same material, teamed with a tartan top for the group's gig.

Joining her bandmates Ashley Roberts, Jessica Sutta, Melody Thornton and Kimberly Wyatt on stage at the famous Sydney landmark, the Pussycat Dolls performed some of their biggest hits, including Don't Cha, StickWitU and Buttons, as well as their latest track When I Grow Up.

The Los Angeles Group are currently promoting their second album Doll Domination, which includes tracks from Nicole's as-yet-unreleased solo album Her Name Is Nicole.

The group is now a quintet after Carmit Bachar quit in March to work on a solo album.

Nicole, who has mixed Hawaiian, Filipino and Russian heritage, started dating 23-year-old Lewis in May after previously meeting at the MTV Europe Music Awards six months previously.

She recently said of her racing beau: 'Lewis is such a wonderful guy. I definitely think he could be The One.

'We might be moving into together soon, he is so kind and generous, we just get on so well.

'Everything is going very well. He is a genius.'
