Jennifer Lopez shows off killer abs during workout before switching into white ensemble for dinner date

She's famed for her enviable curves and hourglass figure.

And Jennifer Lopez proved she's still got one of the best bodies in showbusiness as she stepped out in West Hollywood on Thursday in her workout gear.

The 45-year-old superstar looked amazing in a blue sports bra and skin-tight black leggings as she left the gym.

She showed off her rippling abs and muscular frame as she cooled off with a walk after her intense exercise session, before pulling her grey tee back over her head

Despite having worked up a serious sweat, Jennifer looked red carpet ready as usual.

She wore her honey blonde hair down in loose curls and sported a full face of make-up, adding a touch of glamour with Aviator shades and giant hoop earrings.

The Booty singer was joined by her six-year-old twins Max and Emme, who were clad in adorable casual ensembles.

And Jennifer clearly wanted to make the most of her gym session, showing off the fruits of her labour that evening in a stomach-baring crop top.

The mother-of-two opted for smart white separates during a dinner date at Mr. Chow restaurant in Los Angeles.

Meanwhile, Jennifer's ex-boyfriend P. Diddy arrived at Mr. Chow mere minutes after his former flame left the building.

The rapper, who she dated in 1999, is still on good terms with the singer and recently gushed about her incredible derriere.

He told Access Hollywood Live: 'It's great. It's a work of art. It's something that will go down in history for real it will.

'But also her talent, her drive, her determination, she will never give up.
