Raunchy: Selena Gomez performs at the Hammersmith Apollo on Saturday night

Selena completed the look with a pair of mid-length black boots as she worked her way through the opening songs of a lively set that included hit single Come & Get It, Slow Down and Love Will Remember.

The young star recently jetted into the UK from Paris as she continues her Stars Dance world tour, making her announcement public with  tweet to her 17,000,000 Twitter followers on Saturday.

‘Hi London,’ she wrote, just hours before taking to the stage for the first of two sold-out shows in London.

Away from music Selena has been promoting new film Getaway, in which she stars alongside Hollywood stars Ethan Hawke and Jon Voight.

Despite her best efforts the thriller has failed to make an impact at the box-office, with critics lining up to give it a mauling following its US release on August 30.

Speaking to the New York Daily News, Selena – whose last long-term relationship was with Justin Bieber – admits she finds it hard to ignore the constant rumours and speculation surrounding her private life.

‘It does get to me,’ she said. ‘I’m a human and I feel those emotions of when people talk about you. It’s never a good feeling ‘cause half the time it’s just bull, it’s not real.’

‘In the real world I’ll drive my car to the grocery store and buy myself some food. In the media world it’s like, ‘Oohhh, I drive my car to go somewhere secretive.’ It gets too clouded so I just have good people around me. I’m very picky,’ she admitted.

‘The hardest part (is) just trying to find someone that will just love the core person and not anything else around it.’
