Sienna Miller and Tom Sturridge "stayed together" for their daughter. It was revealed last week that the couple had called time on their relationship, just weeks after they were pictured enjoying a holiday on the Mediterranean islands of Ibiza and Formentera, but insiders claim they had actually separated long before their sunshine break and had been putting on a united front for the sake of three-year-old Marlowe. A source said: "It seems they were staying together for Marlowe. "They'd actually already split up when they went to Formentera. "Recently they've been going to events together but they weren't 'together together'. "They seemed to be trying to keep it up for Marlowe but it looks like they had finally come to the conclusion that things are not working for now.”
