Rita Ora wears sheer corset dress for boyfriend Taika Waititi’s birthday

Rita Ora put on her best dress to celebrate boyfriend Taika Waititi’s 46th birthday.

The “Your Song” singer, 30, hosted a star-studded dinner party for her director beau, wearing a black mesh Dion Lee dress ($890) with a built-in corset that showed off all her curves.

She paired the sexy long-sleeved number with Christian Louboutin knee-high wedge boots ($1,695) and called herself a “cutie with a boot-ie” on Instagram.

Ora shared tons of pics from the event on Instagram; famous friends in attendance included Ashley Benson, Kate Beckinsale, Rami Malek, Kristen Stewart and more.

Ora and Waititi couple have reportedly been in a relationship since early March but “kept things low key,” according to The Sun. However, the pop star and the Oscar winner now seem ready to step into the spotlight, having made their red carpet debut earlier this month at the “Suicide Squad” premiere.

They first sparked romance rumors in April and were photographed having breakfast together the following month. They even briefly added a third to the mix, kissing and cuddling with Tessa Thompson, who stars in Waititi’s upcoming film, “Thor: Love and Thunder.”

Though it doesn’t seem that Thompson made an appearance at Waititi’s birthday festivities, the three appear to be on good terms.

“Is it that big a deal? No, not really. I was doing nothing wrong. It’s fine,” he said of the viral three-way smooch.
