Kim Kardashian West and Jennifer Lopez teamed up at the 2015 Met Gala on Monday to give fans of their famous backsides a treat.

Kardashian and Lopez both stunned on the red carpet in skintight, sheer gowns with embellishments, and both dresses had long, mermaid trains to accentuate their famous rear ends. Kardashian, in Roberto Cavalli, and Lopez, in Atelier Versace, met up inside the Met event, and were photographed walking together arm in arm by Kardashian’s husband, Kanye West.

Both women have been revered for their hourglass figures for years, so the photo, which Kardashian captioned “With my idol,” quickly went viral. Meanwhile, sheer dresses were one of the top trends of the night, with Beyoncé wearing the most risqué.

Lopez wasn’t the only big celebrity idol Kardashian got to meet at the event. She later shared a photo on Instagram of her and Cher, who she said was her fashion inspiration for the night. “I just met [Cher] and told her [she] was my inspiration for my dress tonight! She is so beautiful! So happy I met her,” Kardashian wrote in a separate Instagram post.
