Transcript for Katy Perry's Break-Up With John Mayer Could Inspire New Music
morning America." Time, now, for "Pop news." We begin with this gal, Katy Perry. Is she about to roar about John Mayer? The grammy-winning superstar telling "Cosmo" that her breakup with John will surely inspire some music. There's no bad blood. But says she certainly has material. We'll all be the judge when said songs come out. Asked about how he felt about his breakup being the subject of songs, Mayer told TMZ, writing songs is what you're supposed to do. You're just not supposed to tell everyone you're doing it. This is not the first time Mayer has been associated with an ex's music. You may remember, a little diddy called "Dear John." I wonder if he's amused. He is a muse. A red carpet return for beyonce and Solange. The celebrity sisters making their first public appearance together since that video. That video. The elevator. Jay Z there after the met gala. This time, no drama. Just smiles. The sisters' Gucci style for change event. Dedicated to women's empowerment. Looking good, ladies. Papa can you hear me? Lara can you -- I'm not doing it. Lend me your ear? Visitors to a German museum are waiting in line for hours. Literally, to ask questions through a microphone to Vincent van gogh's regrown ear.

An earful. Oh. You're better than that. You're the one that gets it, usually. Thanks, Lara. You're welcome.
