Janet Jackson shocks fans with X-rated performance at comeback concert

Janet Jackson kicked off the US leg of her first tour in more than seven years sporting a bizarre futuristic catsuit and wild hair reminiscent of her nineties look.

The 42-year-old - who has been in the business for 30 years - delighted fans at the Los Angeles arena with her raunchy performance last night.

Fans were left open mouthed when she plucked a man from the audience, chained him up on stage and began simulating oral sex.

The source told Closer magazine: 'Janet's such an extreme yo-yo dieter. She's piled on the pounds really quickly over the summer, and is now desperate to lose 40lb, just over three stone, in time for her world tour.

'But Jermaine has been stocking the fridge with pizza, fried chicken, chocolate and ice-cream.

The source told Closer magazine: 'It's causing friction in their relationship.'

Janet, 42, has had an ongoing battle with her weight for years. Her yo-yo dieting saw her dramatically gain 4st in 2006, before losing it in four months.

By July 2007 she was pictured looking bulky again after regaining some of the weight.

The sister of reclusive singer Michael Jackson is said to be miserable at her current weight of over 10st.

She now has a nutritionist and a chef, and is sticking to a 'strict diet of 1,700 calories a day'.
