Coldplay star Chris Martin has reportedly bought a new home across the street from his estranged wife Gwyneth Paltrow.

The rocker spent $6.75 million (Gbp4.2 million) on his new pad, which is a stone's throw away from where his kids Apple and Moses live with their mum in Brentwood, Los Angeles.

Martin and Paltrow split in March (14), but have remained close.

Reports suggest the Yellow singer even staged his wife's recent 42nd birthday party in the courtyard of his new digs.
