Oscar winner named 'most beautiful'

Lupita Nyong'o has seen her star rise, including a best supporting actress Oscar for her first major role. In April 2014 she was named People magazine's most beautiful person of 2014.

Nyong'o wowed critics and audiences with her performance in "12 Years a Slave."

The beautiful Kenyan actress has won multiple accolades, including Best Supporting Actress at the 19th Annual Critics' Choice Movie Awards.

"12 Years A Slave," directed by Steve McQueen, was Nyong'o's first feature film.

The actress delivers an emotional performance with her portrayal of Patsey.

"12 Years A Slave" chronicles the true story of Solomon Northup, a free black man who was kidnapped and sold into slavery.

"There is something about acting that's mysterious and magical because there is only so much I can do to prepare and then I have to just let go and breathe and believe that it will come through," says Nyong'o.

In the film, Nyongo's character is a young slave who has a volatile relationship with her erratic slave master.

Nyong'o attends the 14th annual AFI Awards Luncheon in Beverly Hills, California, on January 10.

"In praising me I feel like her (Patsey's) spirit is being uplifted," says Nyong'o, "because what I met in those pages of Solomon Northrup's book was heartbreaking."

Breaks were crucial on the set. "Having those moments of lightness and separation from the work we were doing on set was very important," says Nyong'o.

"12 Years A Slave" has been hailed by many as one of the best movies of the year.

During the 2014 awards season Nyong'o was often hailed for being one of the most fashionable on the red carpet. She made headlines in February for a moving speech she gave while accepting the best breakthrough performance award at the 7th annual Black Women in Hollywood luncheon.

"I remember a time when I too felt unbeautiful," she said. "I put on the TV and only saw pale skin. I got teased and taunted about my night-shaded skin."

The actress told "Today's" Savannah Guthrie that she was moved by People naming her the most beautiful.

"I'm flattered, but flattered sounds like such a flighty word, you know? I'm flattered with, like, gravitas under it," she said.

This year's most beautiful cover issue is the 25th annual for People magazine. The first honor went to actress Michelle Pfeiffer in 1990, and last year's most beautiful person was Gwyneth Paltrow.
