Katy and Orlando have reportedly split after ten months together.
A new report in In Touch Weekly Magazine claims the superstar and Hollywood actor haven't ended on brilliant terms and there is confusion over who broke up with who.
"Not long after Halloween, Orlando confessed to pals that he'd decided to end their relationship. He claimed that he's just not ready to get married and have babies," a source said.
Orlando, 39, already has a five-year-old son Flynn with ex-wife Miranda Kerr. The pair separated in 2013.
Orlando was spotted yesterday trying to stay relatively low-key during lunch in Malibu after reports of his split with Katy emerged.
The Pirates of the Caribbean actor was pictured leaving SoHo House on Tuesday, looking fairly casual in a navy sweater and dark jeans.
Orlando was seen trying to hide his face after he spotted photographers outside the celebrity hotspot before hopping into the passenger seat of his friend's car.
