Lupita Nyong'o is an Oscar nominee and has humor to match her acting prowess.

The "12 Years a Slave" star, 30, filmed an episode of "The Ellen DeGeneres Show" and joked about rumors that she and Jared Leto were dating.

"But I thought Miley Cyrus broke us up," Nyong'o said. "That was the last thing I heard."

She continued, "It's crazy because when I read these rumors, they are so detailed that even I start to question whether they are true or not. I know that I've believed them in the past, so I guess now I can't believe anything."

DeGeneres joked right back, saying "supposedly Portia [Ellen's wife] and I are divorcing, so I'm broken-hearted. That's how I found out, it's really sad."

Nyong'o also admitted that she's not totally used to being on the cover of magazines yet and even tried to buy one at the airport.

"I was trying to be discreet [and buy one] but then the guy behind the counter was like, 'Oh my God, you look like her.' And I was like, 'Yeah, never mind,'" she said.
