Singer-actress Jennifer Lopez was seen showcasing her cleavage in one of her plunging gowns on a date night with beau Casper Smart.

The 45-year-old diva on Wednesday had just dined on traditional Italian fare at Madeo Restaurant with Smart, and seemed to want to make an impact, reports dailymail.co.uk.

Meanwhile, the 28-year-old Smart wore an animal bucket hat with a black hoodie, jeans, and pale Timberland boots.

Lopez wore the same colouful, pleated maxi-dress she had donned earlier in the day while working on "American Idol", but it was clearly a look that translated to her evening of romantic dining.

Her long locks were scraped back off her pretty face into a slick ponytail, working well with her glamorous makeup and retro frock.

On and off couple Lopez and Smart had previously split in July following a nearly four-year relationship. And they have now been seen together again on more than one occasion of late, hinting that things are well and they are back together.

As they left the popular eatery at the end of the evening, the two seemed in fits of giggles in their car before driving off.

The "Dance again" hitmaker is currently judging the 14th season of "American Idol".
