Bradley Cooper Joins Gigi Hadid at Met Gala

joined his girlfriend at the on Monday evening.

The actor, 51, made a surprise appearance at the star-studded event shortly after the supermodel, 31, stepped in front of the cameras in a stunning, see-through gown.

Cooper opted out of walking the iconic steps alongside his girlfriend but later appeared to have met up with her inside of the museum.

After making an undetected arrival, Cooper was seen strolling through the museum in a handsome tuxedo as he admired the exhibit for the 'Fashion Is Art' theme of the year.

While he avoided the pageantry, Hadid took center stage and commanded attention in a daring look while making her entrance on the Met steps.

Her arrival came shortly after her father Mohamed Hadid , which he believed was her at the Met Gala.

For the soirée, Hadid modeled a custom Miu Miu gown made up of a sheer, shimmering material embellished with crystals and embroidered flame details. 

Underneath the sheer dress, she wore a pair of silver, cheeky underwear but opted out of a bra.

The intricate patchwork details across the bodice showed off her toned midriff but protected her modesty.
