The 12 Years a Slave star appeared on this morning's episode of Live With Kelly and Michael to talk about taking home the award for Best Supporting Actress.
The 31-year-old beauty joked she needs to build herself a trophy room for all the hardware she's won this awards season. "I think I have to," she laughed. "I really have to get a two-bedroom apartment and then have this on the mantel right in the middle or something."
As for her Oscar win, Nyong'o said she still can't believe it. "I haven't even slept!" she laughed.
"It hasn't set in but it is overwhelming," she went on. "But at the same time this is a thing that I trained for. It's a thing that I availed myself for, and so I'm just trying to allow myself to absorb it all. It has happened. Twelve midnight came and this did not disappear."
In fact, Nyong'o was so attached to her Oscar trophy last night she wouldn't let it out of her sight! "For the first half of the night, I was being very, very selfish," she admitted. "I wouldn't let anyone even take a picture with it. No, no one was holding it."
