The '12 Years a Slave' star, who is garnering much praise for her work in film, jokingly said on 'The Ellen DeGeneres Show' that Miley Cyrus was the reason behind their break-up, reported Radar online.
"You're actually in tabloids as well, which means you've really made it cause there's rumours that you and Jared Leto are together," DeGeneres joked.
"Ah, but I thought Miley Cyrus broke us up," Nyong'o responded, laughing. "That was the last thing I heard," she added.
Reports about Nyongo's supposed relationship with the 'Dallas Buyers Club' star were thwarted when rumours began to surface that Leto was actually hooking up with Cyrus.
