BBC The One Show fans are all asking the same question about Zendaya's co-star after she appeared on the BBC sofa with him to plug her latest flick.

Zendaya was on the One Show sofa with Mike Faist and Josh O'Connor to promote their new film Challengers, which tells the story of a tennis prodigy turned coach Tashi Duncan.

But although fans loved seeing Spider-Man MJ star Zendaya looking 'gorgeous', several viewers expressed concern for her co-star Mike Faist, who is set to appear in the upcoming sport drama alongside her.
