Taking the plunge! Jennifer Lopez showcases her cleavage in low-cut gown on dinner date with toyboy Casper Smart

She recently reunited with her on/off boyfriend.

And Jennifer Lopez didn't hold back in the wardrobe department as she showcased her cleavage in one of her signature plunging gowns in West Hollywood Wednesday on a date night.

The 45-year-old pop diva had just dined on traditional Italian fare at Madeo Restaurant with her long-term love, Casper Smart, and seemed to want to make an impact.

Get a technocoloured dream dress like J-Lo

Talent shows such as American Idol and America's Got Talent are always about more than just the acts. The judges fashion parade each week is what Fashion Finder tunes in for anyway!

And we once again weren't disappointed by J-Lo's choice of ensemble - she does love her fancy gowns!

The singer/actress certainly knows a thing or two about talent, being such a successful celebrity, but it seems she knows rather a lot about style too - just look at that dress!

Her multicolored pick is by Blumarine and was sent down the runway as part of their Fall 2015 collection back in February. It stood out then and it's definitely standing out now on J-Lo too.

There's something so fun and playful about multicolors - Blumarine has obviously taken a leaf out of Valentino's book after their stand-out spring/summer collection.

We can't give you glitter like J-Lo, but we can do colorful - just check out our array of picks below.

Meanwhile, the 28-year-old choreographer wore a bizarre animal bucket hat with a black hoodie, jeans, and pale Timberland boots, which looked slightly at odds with his lady's glam attire. 

Jen 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 tresses were scraped back off her pretty face into a slick ponytail, working well with her ultra-glam make-up and retro disco diva-esque frock.

On/off couple Jennifer and Casper 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 truly back on for the age-gap pair.

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