The actress chopped off even more hair, debuting her newly-cut and darkened 'do on Instagram on Monday.
"Short hair, don't care," she captioned the close-up, where she's showing off her new bob and a whole lot of smokey eye makeup.
J. Lo had previously cut her hair back in May, before spending some down time in Morocco.
The mother-of-two recently has been sporting a curly lob on the set of her new show, "Shades of Blue," but her wavy tresses may just be a wig. We can't tell.
"Thing about Jennifer is she looks good in everything, and she has amazing hair which makes my job very easy," Jen's hairstylist Lorenzo Martin Lopez recently told People. "We work together so much, we have to constantly switch it up so she looks fresh. I'm pretty lucky."
"She probably has one of the most enviable heads in Hollywood," he added. "I've said it before but when someone has amazing hair, it's easy to create amazing looks."
