The 51-year-old made jaws hit the floor when she took to the stage in thigh highs and a neon bodysuit to perform at the Global Citizen's Vax Live: The Concert to Reunite the World on Sunday night.
This was J Lo's first event and performance since calling it off with A-Rod last month. Showing the ex-Yankee what he's missing, the Let's Get Loud singer strutted her stuff all over the dance floor and left no prisoners behind.
Changing three different times, Jenny From The Block outdid herself every time.
Rocking black leather thigh-high boots with two of her looks -- a yellow zip-up bodysuit and a one-shoulder mini dress -- J Lo looked her best for her first event as a single lady.
J Lo traded in her bodysuit and mini dress for her final ensemble -- a glittering, rose gold feather-coated jumpsuit. The newly-singer star walked the red carpet in a plunging v-neck silver number and looked ready to party despite her recent breakup.
Instead of the MLB player, J Lo's date was her mom, Guadalupe Rodríguez. The singer brought her beloved mama out on the stage with her during the show.
Shutting her performance down with her signature booty shake, J Lo didn't miss a beat as she put A-Rod in her rear-view mirror.
As Radar reported, A-Rod has been desperately trying to win J Lo back but she's not that easy. In fact, she's been spending time with another ex, Ben Affleck.
The former duo caused a stir over the weekend when the Justice League actor was caught leaving J Lo's home in Los Angeles. While Page Six reports, they are just "friends," fans aren't giving up hope on a Bennifer reunion.
A-Rod isn't the only waiting groom that J Lo left before the alter. One day before she was set to marry Affleck in 2003, the couple revealed they were postponing their wedding.
Spoiler alert: they never exchanged nuptials.
