Billie Eilish certainly got heads turning when she made an appearance at the third Annual Academy Museum Gala in Los Angeles on Sunday evening, just hours after calling out Variety for “outing” her on a previous red carpet.

The 21-year-old hitmaker put on a busty display in a brown two-piece pinstriped suit for the star-studded event.

Billie, who recently spoke out about her relationship with her ex Jesse Rutherford, sported a striped blazer coat that exposed her ample cleavage with a matching maxi skirt that covered her whole bottom half.

The What Was I Made For singer accessorized her chic look with a brown silk wrap that she tied around her head with a pair of thin-rimmed glasses.

She also upped the ante of her look with several glitzy necklaces and rings for the annual bash.

The singer posed and beamed a bright smile for the cameras exposing a fake gunmetal coloured tooth.

But Billie’s appearance at the event came just hours after she also accused Variety of “outing” her during the publication’s Hitmakers event that took place on December 2.

During the interview, Billie revealed that she is “attracted to women” and was surprised that “people didn’t know”.

Shortly after the revelation, the Grammy Award winner lost almost 10,000 followers on Instagram and a further 75,000 the next day.
