However, the 34-year-old "Burnt" actress and the British actor don't meet up regularly now, reported E! online.
"We don't see each other that much. I care about him enormously," Miller said.
The couple met while costarring in the 2004 film Alfie together, and got engaged at Christmas of the same year.
They call it quits the very next year after Law, 43, was caught having an affair with the nanny of his children.
The couple gave their relationship a second try in 2009, but called it quits for good in 2011.
