Dame Helen Mirren picked up the best actress Oscar for her role in The Queen. The British beauty made a guest appearance on today’s Oprah’s post-Oscar TV special and shared about her Oscar-winning experience.

Helen, 61, brought along her red carpet gown, a champagne-colored plunging V-neck Christian Lacroix, and laughed about not having to wear underwear because her dress was custom-made.

“You look at the inside of this dress. It’s as beautiful as the outside. It’s fantastic. It was all made for me, so I didn’t have to have any underwear.” While grabbing her chest, Helen continued, “It held me like two angel’s hands.”

Hahaha. Helen’s such a hoot! Watch the video below!

Helen Mirren is also rumored to have tea with Queen Elizabeth.
