J Lopez takes the plunge

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.

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 colourful, 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.

Jennifer was seen walking in sky-high heels earlier in the day, beside American Idol’s longtime host Ryan Seacrest outside the Hollywood studio.

The Feel the Light singer rocked her trademark hoop earrings as well as a trendy marsala hue on her eyelids and lips for the daytime filming.

Jennifer currently judges the 14th season of American Idol, which airs Wednesdays and Thursdays on Fox, a role she’s had for several years with just a brief hiatus in between.

The busy Booty hitmaker will soon film the drama Shades Of Blue in Manhattan, and Universal Picture’s Mothers I’d Like To . . .

The Home actress will star and serve as producer on the comedy described as ‘‘Bridesmaids meets First Wives Club.’’ — dailymirror.
