It may have been the long awaited American Idol results show, but Jennifer Lopez refused to let either Phillip Phillips or Jessica Sanchez upstage her tonight.

The 42-year-old singer and actress poured herself into an ultra low cut studded crop top which showed off her famous curves to the maximum.

With her long brown hair loose and tousled, the judge certainly got stuck into her performance of new single Goin’ In.

Surrounded by a menagerie of dancers clad in white, the singer certainly worked up a sweat during the number.

She began the number showing a little less flesh in a long white vest top before stripping off to reveal her washboard stomach and toned arms to the maximum.

She then joined reggaeton duo Wisin & Yandel for her recent single Follow The Leader.

It is perhaps unsurprising that J-Lo was taking full advantage of appearing on one of America’s top rated TV shows.,

She recently revealed she is unsure whether she will take part in a third season of the show.

‘I don’t know I enjoy it. I really do enjoy it,’ she said on the Ellen DeGeneres talk show last week.

‘This is my second year. I don’t know if I can go for a third year. I miss doing other things. It really does lock you down.’

Meanwhile, a source close to the singer told E!: ‘She’s just too busy.’

The star is about to embark on a high-profile concert tour with Enrique Iglesias, which kicks off this summer in South America and the US.

In addition she is also planning to go overseas for a worldwide tour in the autumn, and will be on the road until at least the end of the year.

This will make it very difficult to attend the show’s tapings, as the next round of Idol auditions will start while the star is overseas.

Jennifer is also hoping to lighten her schedule next year, and is even considering a break so she can spend time with her four-year-old twin children Max and Emme, who will be starting school soon.

Meanwhile, at the premiere of new film What to Expect When You’re Expecting last week she said: ‘It is just like any working mother’s dilemma.

‘It’s tough. It’s a balancing act. You put them first and then you have all these other things that you have to do, that you have to give your time to as well, and you have to make sure that they’re OK in the process.’

She’s in fashion: Jennifer’s sartorial choices on Idol this season have been a hit with viewers

But the show’s executive producer Nigel Lythgoe told TMZ he is desperate for her to remain, saying: ‘We want her back. I want her back.

‘I know how much she loves doing the show and how much she cares for the kids.’It’s a business. She has to weigh everything. I know she’s gotten lots of offers to do movies and other things.”
