Chris Martin said the F-word while promoting Coldplay's Super Bowl 50 halftime performance on Thursday, and we don't mean "fumble."

"It's a difficult question to answer," Martin responded to a reporter's question during the live TV broadcast.

"Are you saying which part of our show will we f--k up terribly?" he asked with a laugh.

It's not the only thing making headlines ahead of the Super Bowl. The band's reported set list won't include their new song "Hymn for the Weekend," which features fellow Super Bowl 50 halftime performer Beyonce.

"It only just came out, so I don't think it would be quite right," Martin said of the decision not to highlight “Hymn.”

Nonetheless, Queen Bey will join Coldplay on the big stage Sunday and the band knows the performance could be a game-changer for their careers.

"Everyone who does this show knows it's the biggest honor," Martin gushed.

More than 100 million viewers are expected to tune in to Super Bowl 50, but where will Martin's children Apple, 11, and Moses, 9, be watching?

"I hope [they'll be with me]. It's hard to get tickets though," Martin joked. "My son [Moses] designed my shoes. I asked him, 'Please, could you make me some Super Bowl shoes?' He made two pairs. One is for this and the other is for the Super Bowl."
