Chris started off with Rihanna, who's featured in the band's new video for Princess of China, calling her "the third most attractive woman in the world." Where's Gwyneth Paltrow on that list? Chris ranked his wife at first and second. Chris went on to clarify that Rihanna is a distant third.

Coldplay launched their current tour in Canada, which Chris referred to as a "homecoming," as the city marked the first place the British band ever played in North America.

"This is the first time we've really been able to kind of include everybody," Jonny Buckland said, explaining what makes this tour different. Chris added, "We have this wristband light thing that everybody gets in the audience, which is really phenomenal to look at when you're playing on stage."
