Taylor Swift was worried when her friend Ed Sheeran lost his cell phone at the BRIT Awards because whoever found it would have access to all the goofy videos she sent him.

The pair became close friends after they teamed up to collaborate for Swift's last album, Red, and her new number was among those on his cell phone when it vanished at the London prizegiving last week.

The phone, which also contained music for Sheeran's next record, eventually turned up, but Swift admits anyone who picked it up would have seen some strange personal footage from her.

She tells Britain's Capital FM radio station, "Someone's gonna get videos of me having a conversation with my cat that I sent Ed... and like YouTube videos and stuff like that. He's one of my best friends... Legitimately."
