She has become well known for her enviable curves, and in particular her toned derrire.

So perhaps it was unsurprising that Jennifer Lopez's toy boy boyfriend Casper Smart couldn't resist grabbing his girlfriend's rear end several times in her new Dance Again video.

The scantily clad couple were positively smouldering in several sexy scenes for the full video version of the song, which debuted on American Idol tonight.

While introducing the video, Idol host Ryan Secrest took the chance to quiz the judge on her
relationship with 24-year-old Casper.

'Is there any special chemistry with you and any of the dancers' he asked, much to Lopez's obvious embarrassment.

She swiftly changed the subject, saying: It's fun and dancy and full of joy.'

The video sees Lopez strut around in a strapless
black basque and heels while a shirtless Casper dances an intimate
number with his girlfriend.

And the couple couldn't seem to keep their hands off each other as they cavorted in several scenes together.

The
steamy video also features Lopez crawling over a menagerie of scantily
clad models in a room and dancing enthusiastically with Casper while
covered in gold glitter.

Casper appears shirtless throughout the video, showing off his large number of tattoos on his muscular torso.

At one point, the couple look to be recreating
the famous upside down Spider-Man kiss with J-Lo sporting a low cut top
and a shirtless Casper leaning in for the clinch.

Other shots show the stunning
42-year-old star sporting beachy tousled hair and subtle make-up while
smouldering at the camera as she lip syncs to the catchy number.

The

wet sand, while another shows her swishing her hair and dancing wildly.

Casper follows in the footsteps of Jennifer's ex boyfriend Ben Affleck who famously appeared in J-Lo's 2002 video for Jenny from the Block

Ben
and Jen were shown cavorting on a yacht, with the Academy Award winning
actor nuzzling into J-Lo's bikini clad body and untying her hot pink
top.

Now married to Jennifer Garner with
three children, Affleck – who was engaged to marry the Latino singer –
now says he regrets doing the video.

Casper,
who is usually in the audience during American Idol, has been
photographed with his girlfriend everywhere from Miami Beach to Brazil
and Mexico where he filmed Dance Again.

'There is a lot of love between [them], he treats her like a queen,' People magazine reported.

However, Jennifer, who split from
husband Marc Anthony last July after seven years of marriage, has
remained fairly tight lipped about her new relationship with Casper.

'He's adorable. But you already see that,' she recently told Vogue. 'He
really is [sweet].

'He's a good egg. I don't want to talk about it too
much. It's my private thing.'
