Flower power: Jennifer Lopez, 46, slips into a bizarre floral tracksuit as she goes last-minute shopping with toyboy beau Casper Smart, 28 

She's no doubt excited for a fun family Christmas with her seven-year-old twins, Max and Emme. 

But Jennifer Lopez made sure to squeeze in some quality time with the main man in her life as she enjoyed a spot of last-minute shopping with her toyboy beau, Casper Smart, 28, on Christmas Eve. 

The singer, 46, ditched her usual glamour in favour of sporting a bizarre floral tracksuit and high-top trainers as she bought her last few presents at Neiman Marcus in Los Angeles.

Cute couple: Jennifer Lopez made sure to squeeze in some quality time with the main man in her life as she enjoyed a spot of last-minute shopping with her toyboy beau, Casper Smart, 28, on Christmas Eve

Wearing her brunette hair scraped off her face into a topknot, the American Idol judge opted for low-key make-up and covered her face with a pair of mirrored shades.

Casper, who JLo has been dating on and off since October 2011, kept things equally casual in an all-black ensemble, which he teamed with his signature baseball cap and shades. 

Last week, Jennifer posted a sweet snap of her adorable twins Max and Emme, seven, posing for a fun festive snap in holiday outfits. 

In the snap, Emme wears reindeer-inspired sunglasses and a milk & cookies shirt as she showcases some of her mother's attitude.

While Max sports Christmas tree sunglasses while holding up $20 to the camera.

'These two at it again!!' the 46-year-old mother captioned the adorable portrait. 

She then added the hashtags: '#christmastime #holidayspirit #Emmeisreadytoparty #Maxisreadytogoshopping #coconutchristmas'

The singer, actress, dancer and TV host shares the twins with ex husband Marc Anthony.

Lopez gave birth to Maximilian David and Emme Maribel, in Long Island, New York on February 22, 2008.

Currently filming the latest (and last) series of American Idol, Jennifer is preparing to embark on a four month residency in Las Vegas in 2016.

Beginning in January and ending in May, the residency will see the star earn her first ever headlining residency.

The live-in marks her first of the sort and is entitled All I Have. It will kick off at the AXIS Theater inside Planet Hollywood on January 20.

The On The Floor hit-maker will initially play a total of 20 concerts at the venue but it's set to be extended to 40 for three years.

But while she is throwing herself into her music career, January will also J Lo return to acting; when her police drama Shades of Blue will hit TV screens.
