Birthday Girl Gigi Hadid Steals The Spotlight In Gold Sequin Mini Dress

The supermodels look incredible in their party dresses - a stark contrast to their laidback street-style. Gigi wears a gold sequin dress which paired with glittering Christian Louboutin heels. The newly single blonde finished-off her look with wavy tresses and metallic makeup.

Bella, 21, opted for an animal print dress and '60s inspired hair and winged eyeliner. The brunette pulled her locks back into a fun ponytail.

Models Lily Aldridge and Olivia Culpo were also spotted heading to Gigi's birthday party, as well as a huge cake with 'GIGI' written on it in pink icing.

Earlier in the day, little sister Bella took to Instagram to wish her best friend happy birthday, see her heartwarming messages below.
