Rose Leslie, 30, an actress in the popular series “Game of Thrones,” was spotted with her co-star and boyfriend, Kit Harington, at the Olivier Awards in London.

While the actor who plays Jon Snow was suited up in a classic tuxedo, Leslie wore a sheer red corset-style dress by Christian Dior.

But it wasn’t just the color and the design that caught the attention of the photographers, it was the fact that Leslie purposely showed off her black underwear by posing with her back to the cameras.

She teamed the dress with black sparkling peep-toe heels.

The Olivier Awards, held at the Royal Albert Hall, hosted some of the biggest names in British theater and entertainment.

Several other celebrities were also spotted on the red carpet, including Amanda Holden, Billie Piper, Louise Redknapp, Gary Barlow and Sheridan Smith.

Holden, the judge of “Britain’s Got Talent,” brought a splash of color to the event in her bright yellow floor-length dress, while Piper won the Best Actress award for her role in “Yerma” and wore a strapless feathered dress.

Smith, a British actress and singer, wore a black floor-length number, while Jamie Redknapp’s wife Louise wore a summery floral dress, complete with keyhole neckline.

She completed her look with a black clutch and left her light brunette waves down.

Gary Barlow, a member of the British pop group Take That, graced the event in a black three-piece suit.

His “Let It Shine” co-host, Amber Riley, also attended the event in a blue sequined floor-length gown that had a sheer neckline showing off her cleavage.

While Kit and Rose have been dating for quite some time now, they have kept their relationship quite private.

This was one of the rare occasions when they were seen together in public.

The couple met on the sets of “Game of Thrones” where they played the roles of Jon Snow and Ygritte, respectively. They started dating in 2012 but broke up in 2013.

However, they rekindled their romance in 2016 and have been going strong since then.

The Olivier Awards are held annually to honor the best talent in British theater.

This year’s nominations included productions such as “Harry Potter and the Cursed Child,” “Groundhog Day,” and “Dreamgirls.”

The Best Actor award was won by Jamie Parker for his role in “Harry Potter and the Cursed Child,” while the Best Actress award went to Billie Piper for her role in “Yerma.”

Rose Leslie has been working in the entertainment industry for over a decade now.

Apart from “Game of Thrones,” she has also appeared in several other TV shows and movies.

Some of her notable roles include Gwen Dawson in “Downton Abbey” and Maia Rindell in “The Good Fight.”

She is also known for her theater work and has been part of productions such as “Uncle Vanya” and “Antigone.”

Leslie’s quirky fashion sense is not new. She has been known to experiment with her outfits and has been spotted wearing some interesting pieces in the past.

At the 2017 Golden Globe Awards, she wore a stunning black lace dress by Elie Saab that was quite different from the usual red carpet gowns.

She also wore a beautiful red dress by Erdem to the premiere of “The Last Witch Hunter” in 2015.
