Jennifer Lopez's abs made an appearance Wednesday in West Hollywood, California. The singer was spotted pulling a tank top over her purple sports bra and black leggings outside the gym. Later that evening, she was photographed heading to dinner in a white midriff-baring ensemble.
In May, Lopez revealed she tried the 22-day vegan diet that Beyonce and Jay Z completed last year.

"I did the vegan 22-day plan and it was really good, and I kept on with it for a few more weeks and now I've incorporated a little bit of fish here and there," she told Ryan Seacrest. "But I've got to tell you, I enjoy it. I enjoy eating that way. I never did and I didn't know how good you can feel when you put healthy stuff in your body. I was so used to just eating the way I grew up."

It's been 14 years since J.Lo wore that plunging Versace dress to the 2000 Grammys, but this image is still fresh in our minds:

Lopez gave fans green dress déjà vu when she stunned in this plunging leotard at a free performance in the Bronx June 4:

The updated version of her dress wasn't the only thing to bring on the nostalgia, either. Of course, the Bronx native performed "Jenny From The Block" for her hometown crowd along with a slew of her older hits. Lopez also enlisted fellow New Yorkers Ja Rule, Fat Joe and French Montana to perform onstage with her.

The 44-year-old recently gave another nod to her iconic gown with a similar outfit in her video for "I Luh Ya Papi." As for where the real dress is today? Lopez told Harper's Bazaar that it's hanging up on a mannequin in her spa. We can only hope that one day she'll break out the real deal again.
