The amazing photo, which Kardashian shared via Instagram, shows the two super-famous booties side by side, accentuated by their stunning gowns which hugged tight over their derrieres before flowing out in cascading fish tails onto the floor behind them.
In the photo, Lopez is seen to be marginally taller than her reality TV buddy, and has linked her left arm through Kardashian's right as the pair walk very closely together through New York's Metropolitan Museum of Art.
Their famous backsides have only the tiniest glimmer of daylight between them and as they appear next to each other, the Kardashian butt appears to be slightly more curvaceous than Lopez's infamous booty.
Both 34-year-old Kardashian and 45-year-old Lopez are wearing super sheer dresses, showing off much of their underwear-free behinds through the panels in their stunning gowns.
"With my idol," Kardashian captioned the snap, adding that the photo was taken by her admiring husband West.
