Jennifer Lopez flashes her incredible abs and trim figure after a gruelling workout in Los Angeles

The singer and actress looks incredible at 45 and was seen once again heading from a gym work out flashing her toned stomach

Jennifer Lopez gave birth to twins - but you wouldn't know - because she's always looking SUPER trim.
The sexy singer, who is now back on the market after splitting from Casper Smart after two and a half years, showed off her toned stomach in a cut-off blue t-shirt, tight black gym pants with a purple waistband and white and yellow trainers in Los Angeles.
Jen, 45, looks incredible for her age and was seen heading to her car after a gruelling workout with her hair tied up in a bun and a pair of aviator sunglasses on.

She didn't appear to have a scrap of make-up on during her gym trip on Tuesday, deciding to go au naturel, and looked fantastic with glowing skin and full lips.
Jen glammed up her fitness look with a pair of sparkling stud earrings and showed off her perfectly manicured powder blue nails as she was met by waiting paparazzi.
The star doesn't look very different from when she was Jenny From The Block back in the early days of her acting and music career. We want to know her secret!

Meanwhile, the star also paid tribute to her Jack co-star Robin Williams this week, after it was reported he'd been found dead at his home aged 63 from an apparent suicide.
Jennifer played Robin's fifth grade teacher in the 1996 comedy, which saw the actor play a 10-year-old boy who looked like a 40-year-old because of an aging disorder.
The singer posted on Twitter: "Sad, sad, day... My condolences to Robin’s family. He brought light to every room he entered & was a true comedic genius. #RIPRW"
