Jennifer Lopez stuns in tiny bikini at age 51

Jennifer Lopez has sent her 131 million followers into a frenzy after sharing a seductive bikini snap, but many have questioned one thing.

Jennifer Lopez has yet again sent her 131 million followers into a spin after showcasing her killer abs in a tiny bikini.

The Hustlers star is not only one of the hardest working people in showbiz, but in the gym too, and it shows.

The mum-of-two (she has 12-year-old twins Emme and Max) took to her Instagram on Monday sharing a selfie of her posing in a floral bikini with her toned figure on full display – and it left some fans questioning her age.

“OMG it’s impossible 51? JLo latina Vampire,” one follower wrote.

“I wanna look like that at 51 too. Oh sorry I mean 21. You are glowing damn,” said another.

“How is this happening? Best looking 51-year-old EVER! How can she still look like when she first came on the scene,” a third person commented, while a fourth wrote, “That’s it. No sugar no carbs diet here I come.”

In February this year, the singer left fans baffled yet again after sharing another sizzling bikini snap.

“Relaxed and recharged,” she captioned the photo, with fans quick to point put she is a “ageless queen”.

“OH MY GOOOD! I am officially completely sure that you are 30 years old and have deceived humanity all this time,” one stunned fan wrote.

Others described her sculpted physique as “insane”, “perfect” and “goals”.

For those wondering, the star never skips a workout.

In preparation for her most recent movie Hustlers, JLo told fans she’d given up sugar and carbs as part of a 10-day challenge.

Cutting the two food groups was a suggestion made by her trainer, Dodd Romero, to help her prepare for her role, she said on an episode of The Ellen Show.

“(The challenge) was really hard. Not only do you get a headache, but you feel like you’re in an alternate reality or universe. Like, you don’t feel like yourself. You realise that you’re addicted to sugar,” she said.

“I am 100 per cent convinced that working out is part of what makes me so happy,” she told Hello! in 2016.
