Oscars: Lupita Nyong'o Reveals Her Must-Have for the Big Day

First-time nominee also talks about preparing an acceptance speech

The last thing Lupita Nyong'o wants to do if she wins an Oscar on Sunday is botch her acceptance speech.

That's why the 12 Years a Slave star is giving some thought to what she'll say—just not too much thought.

"How I feel about these things is that you have a one in five chance of being called and I don't like to be surprised and I don't like to be tongue-tied, so I definitely think that I will think about what I'd like to say if indeed I get that opportunity," Nyong'o told me last night at the LoveGold party in her honor at Chateau Marmont.

"I'm not going to overthink it," she said. "You want it from the heart but you don't want to think about it so much…So, yeah it's crossed my mind and I'm definitely thinking about all the people that I have so much to thank for."

And this may be Nyong'o's first time at the Oscars, but she knows one thing she'll definitely do.

"I'm going to start off with a massage," she said. "That's what I did before the Golden Globes and I think that day went very well. So, I think the Oscars deserve a massage. I deserve a massage."

She sure does.

"I like deep tissue for sure," Nyong'o said. "I like to know I'm getting a massage."

And like she told me earlier this week, she's been "really enjoying playing dress up" this awards season.

Makeup is usually by Nick Barose. "He comes with proposals of things to do and we collaborate and come up with the perfect look for what I'm wearing," Nyong'o said. "It's a collaboration and I like to give him creative license."

The Yale graduate has two hairstylists, Ted Gibson and Larry Sims. It will be Sims who will take care of her on Sunday. "He gets his whole body involved in his proposals for my hair," Nyong'o said. "He has all sorts of dances showing me what he's going to do. Yeah, he definitely vogues. We really get into it and that's fun."

And at the end of the day, it's all about avocado oil to help keep her skin, well, amazing. "It's actually quite good to get makeup off," Nyong'o said. "It's gentle on your skin. It's very gentle."
