Both Gigi and Calvin shared pics and a video on the social platform. Gigi celebrated her 21st birthday on April 23.
“I love you,” Gigi captioned one photo of Taylor, who had a yummy looking cake for her pal.
“Cake(s) on a plane,” Calvin wrote on his Snap of Gigi and Taylor, referencing the 2006 film Snakes on a Plane.
“Thank you guys so much for having me on your romantic date,” Gigi said in a video.
“Thanks for coming on your birthday weekend, that’s great. Wow,” Taylor responded.
