JLS heartthrob The Saturdayssinger Rochelle Wiseman.

The Beat Again star blamed the pair’s busy touring schedules, which meant they rarely saw each other. “I’m on tour for two months and then as soon as I come off, she’s on tour for six weeks,” he explained. “We’re both very sad. It was a very tough decision but we truly believe – both of us – it’s the best for right now.”

But Marvin didn’t rule out them getting back together in the future. “We’re still very good friends and we still talk daily. She’s an incredible girl,” he said. “Situations could be different in the future. We wouldn’t have committed if we hadn’t thought we were right together. Who knows what will happen.”

For now, the couple are still living together in their west London home because they are both too busy with work commitments to move.

JLS perform their new single Love You More on The X Factor tonight.
