The 32-year-old Avengers actress wore a stunning floor length baby blue and black dress.

The gorgeous gown had lace detailing all over as she accessorized with a metallic style clutch.

Her pixie blonde locks were styled in a messy side parting as she went for a natural but flawless make-up style.

She added dangle earrings to complete her evening attire.

Meanwhile the actress is also promoting her female dominated movie Rough Night, which comes out this June.

A male stripper ends up dead at a Miami beach house during a bachelorette party weekend.

The funny cast includes Zoë Kravitz, Kate McKinnon, Jillian Bell and Ilana Glazer

Modern Family’s Ty Burrell and Teen Wolf’s Colton Haynes are also in the film.

And it seems she will be arriving at the premiere this summer with an interesting guest.

The blonde stunner recently realized she has a doppelganger – and even invited her to party with her at the Rough Night premiere.

She posted a video directed to a 72-year-old grandmother called Geraldine, after a Reddit user named denverjoel shared a photo of his relative who bears a striking resemblance to the Ghost in the Shell star.
