In honor of what would've been Gigi's 18th birthday on May 1, Vanessa unveiled a special edition design for the Nike Kobe 8 "Mambacita," the sneakers based on the teen's nickname.

The new pattern featured black butterflies on a white background with golden accents, including a heart-shaped pendant baring the "Mambacita" logo. The design also included Gigi's name and her basketball jersey number written in black letters on the heel of the shoe.

"MAMBACITA," Vanessa wrote on Instagram. "5/1/2006 GIGI."
