Coldplay singer Chris Martin is reportedly helping U2 with their new album. He was spotted in a studio with them in New York.

The Coldplay frontman reportedly joined the Irish rockers – Bono, The Edge, Adam Clayton and Larry Mullen Jr – at Electric Lady Studios, where they have been working on their 13th album with producer Danger Mouse, reports contactmusic.com.

According to fan site atu2.com: “Our reporter saw Coldplay’s Chris Martin arrive, followed by Larry Mullen Jr. about two minutes later.

“Shortly after that, a van arrived with three guitars – each with a white label that said ‘U2/Edge’ – and our reporter actually helped bring the gear into the studio. He saw Larry and Chris Martin together in another room before heading back outside.”
