When the 22-year-old Oscar winner crossed paths with the former Sex and the City star at the Metropolitan Museum of Art's Costume Institute Gala, not even Parker's Philip Treacy fascinator could compete.
With Lawrence wearing the Voilette by Jennifer Behr paired with a Dior dress, and Parker, 48, wearing legendary milliner Treacy's creation, there seemed to be an accessory face-off when the two crossed paths.
But the Silver Linings Playbook star couldn't resist running her fingers through Parker's headpiece, resulting in laughter and an even more hilarious photograph.
Although she walked the red carpet with designer Raf Simons, Lawrence was recently spotted dining with one-time boyfriend actor Nicholas Hoult, who was also in attendance.
"We're friends, we're about to work on a film together, so ..." Hoult told PEOPLE on the red carpet.
