Jennifer Lopez has wowed fans in a plunging black jumpsuit as she arrived at a dance studio in Los Angeles.
The backless outfit showed off her bra, and she added large sunglasses and black handbag.
She revealed in a new issue of her newsletter On The JLo that exhaustion in her 20s left her feeling like she was losing her mind, but now puts her healthy appearance down to getting enough sleep.
The 52-year-old said that a doctor told her that her health was being affected by exhaustion as she running on “three to five hours” of sleep a night.
She said: “I’d be on set all day and in the studio all night and doing junkets and filming videos on the weekends. I was in my late 20s and I thought I was invincible.”
Lopez added that the result of getting enough sleep was she occasionally wakes up and thinks: “Wow! I just lost 10 years off my face!” and that “sleep to me is the most underrated beauty secret out there.”
Her documentary Halftime is set to premiere at the Tribeca Film Festival before appearing on Netflix on June 14.
