Jennifer Lopez pυts her perfects pins on show as she slips into a ‘Lo’ cυt dress for Jay Leno appearance

American Idol judge Jennifer Lopez took a step in front of the panel tonight for an appearance on the Jay Leno show.

While the 42-year-old singer may make weekly TV Appearances on the Fox talent programme, her legs are always kept under wraps behind her desk.

But tonight J-Lo took the chance to show of her perfect pins as she chatted with Leno.

Fine form: The singer, 42, showed off her figure in a plunging black dress, which she teamed with Christian Louboutin heels

The ‘American Idol’ judge revealed she has nicknamed three-year-old twins Max and Emme – her coconuts.

They were given the name as babies because she felt they resembled the hairy fruit.

She explained: ‘The twins are so good, they’re about to turn four.

They’re my coconuts, that comes from when they were little and in their cribs and started growing hair, it looked just like a coconut to me, they both look like coconuts.

‘I have this beautiful necklace which was given to me at Christmas, there are two coconuts and their initials on it’

Jennifer – who is now dating dancer Casper Smart – also revealed her former boyfriend P. Diddy gave her the best advice she has ever received when she was beginning her career, even if he didn’t express his message very kindly.

She told TV talk show host Jay Leno: ‘I had a lot of mentors, Puffy aka Diddy now, when I first met him I was making my first album and he gave me a lot of insight into the music business, he helped me a lot.

‘He did say one thing to me that was funny, I was recording music for my first album and I played a song for him and said, ‘What do you think’ and he said, ‘I hate it.

It’s not good, it won’t be a hit,’ and I said, ‘I love it’, standing up for myself,’ and he said, ‘Good, you can listen to it in your living room because you’re the only one.’

‘It stayed with me because he’s right – as an artist it’s not just about touching you, everybody has to relate to it, that’s the main thing so I really learned from that, even though he was tough with the message.

‘[But] the song was still on the first album.’

Meanwhile the mother-of-two – who is dating dancer Casper Smart, 24, following her split from husband Marc Anthony – has recruited controversial filmmaker Brett Ratner to direct the second video from her album Love.

Ratner – who has directed videos for Madonna and Mariah Carey – was forced to step down as the Academy

Awards producer after making a homophobic remark during a question an answer session last year for his film Tower Heist.

Lopez is still to shoot the video, which will apparently depict  ‘an urban outdoor adventure game played by the singer and and a crew of six stunt performers,’ according to the publication.

It will get its world premiere during an episode of American Idol.
