Jennifer Lopez, 57, flashes her bra in a plunging white shirt as she steps out during Milan Fashion Week

Jennifer Lopez flashed her bra in a plunging white shirt as she enjoyed yet another fashion moment at Milan Fashion Week on Monday night. 

The pop superstar, 57, exposed her lingerie under an open white shirt which she had teamed with high-waisted palazzo style trousers.

Adding some inches to her height, she wore a pair of high platform heels and carried a small black Dolce And Gabbana bag in hand. 

No doubt Jennifer will attend Brunello Cucinelli's show on Wednesday. She and her ex-husband Ben Affleck, were big fans of the fashion house. 

And on Friday, Jennifer will be flying over to Cannes, France, for the NRJ Music Awards. 

The singer is nominated alongside the likes of Harry Styles, Ariana and Bad Bunny, to name a few. 

The week before, Jennifer was seen working out in Santa Monica and has spoken at length about the work she puts into her fitness regime. 

She told Extra in June: 'You know that you're gonna be on screen. You gotta be prepared... in the gym and eating right. 

'It's about eating healthy and eating the right things and working out and being consistent. I say these things all the time.'

She also focuses on weight training in order to keep her muscles strong, and explained on CBS Mornings that she now maintains a workout routine that is 'smarter, not harder'.

Jennifer added: 'That's what my trainers and I think about a lot. It's like, I have 40 minutes for you right now and we need to maximize that, and we do.'

'I lift heavy, I do a lot of weights now because as you get older you need to start doing that in your 30s.'

'And you need to do that because, even if you're like, into cardio and you want to be slim or drop weight or whatever, muscle is the thing that burns fat.'

The music artist further explained that 'as we get older, we lose the muscle. So, we need to build the muscle to keep a youthful appearance, you know?'
