What better way to pay tribute to your big sister on her birthday than by wearing a swimsuit featuring her name? Bella Hadid did just that to honor Gigi Hadid's monumental 21st over the weekend, showing off her toned physique in a black one-piece that had "Gigi" written across the front in gold lettering.
Bella took to Instagram yesterday to show off the sexy suit ($220, brunamalucelli.com) that she donned during a trip to the beach in Malibu, Calif., captioning the picture: "#1 fan." The duo's mom, Yolanda Hadid, also 'grammed the photo and wrote: "Celebrating 'GIGI' day........ @bellahadid #Sisterhood #PointDume."
And it looks like the blonde bombshell had one busy weekend. After kicking off her celebrations with all of her gorgeous siblings and then spending a day at the beach, Gigi headed to Coachella last night with BFF Taylor Swift to watch Calvin Harris perform.
