COLUMBIA (WACH/AP) â?? The 86th Academy Awards aired live on ABC from the Dolby Theatre in Los Angeles, with host Ellen DeGeneres.
Lupita Nyong'o won the Academy Award for best supporting actress for her harrowing portrayal of a slave who's caught her sadistic master's eye in "12 Years a Slave."
It was the first Oscar nomination for the 31-year-old Nyong'o, and she won it for her film debut.
Not just a breakout movie star, the Mexican-born actress of Kenyan descent has also made a huge splash in the fashion world.
Ellen DeGeneres' goal of setting a retweet record with her star-studded selfie was achieved before the Oscars telecast was even over.
During a comic bit, the Oscars host prevailed upon actor Bradley Cooper to take a picture with her and several other stars crowding around, including Meryl Streep, Jennifer Lawrence, Kevin Spacey, Angelina Jolie and Brad Pitt.
Twitter also sent out an apology because all of the retweeting disrupted service for more than 20 minutes after 10 p.m. ET.
`12 Years a Slave' won best picture Oscar.
In his first Oscar nominee, Matthew McConaughey has won the Academy Award for best actor for his performance as a desperate and determined AIDS patient in "Dallas Buyers Club."

It was the seventh Oscar of the evening for "Gravity" and the second for Cuaron himself. Earlier in the evening he shared in the Oscar for film editing.
"Let It Go" from the Disney musical "Frozen" won the Academy Award for best original song.
