The 38-year-old founding member of hip-hop band 'Black Eyed Peas' has offered 'The Promise' hitmaker his mansion until she is house-hunting in LA, reported Sun online.
His multi-million pound mansion in Los Feliz includes a state-of-the-art recording studio and infinity pool.
"Will likes to make sure Cheryl's being looked after in LA. He's not around over the summer and would rather the place is lived in than left empty," a source said.
