Jennifer Lopez arrives at the MTV Video Music Awards at Radio City Music Hall on Aug. 20, 2018 in New York City. 

Jennifer Lopez is feeling -- and looking -- like a superhero.

With just three shows left in her Las Vegas residency Jennifer Lopez: All I Have, the singer took to Instagram on Sept. 26 to share an update. "Feeling like superwoman after the show tonight! When I started this run I thought omg 15 shows in 27 days that’s a lot... but I made a promise to myself that instead of letting it wear me down I would be even stronger at the end of it...I will work out and be in the best shape of my life," she wrote. "There were moments I was tired and there was travel and I had to fit in my workouts where I could... but here we are with only 3 shows left!! And I am having so many emotions but mostly just feeling strong, happy and grateful!"

Lopez has been making music for almost two decades, and recently accepted the MTV Video Vanguard Award at the VMAs, landing a spot alongside superstars such as MadonnaRihannaBritney SpearsKanye West, and David Bowie. Her Vegas residency concludes on Sept. 29.
