Lupita Nyong'o has sidestepped questions about her rumoured romance with Jared Leto during a US TV interview.

The 12 Years A Slave star is said to have become close to the actor, but when quizzed about it on The Ellen DeGeneres Show she joked that Miley Cyrus had split them up.

When host Ellen asked whether she is dating the Dallas Buyers Club star, Lupita quipped: "But I thought Miley Cyrus broke us up, that was the last thing I heard?"

She went on: "It's crazy, cause when I read these rumours, they're so detailed that even I start to question whether they're true or not. I know I've believed them in the past and now I guess I can't believe anything."

It was reported earlier this month that Lupita and Jared were getting cosy.

However, a later report suggested the actor was actually becoming close to pop star Miley.
