The two stars, who were once involved in an on-again, off-again romance, seem to be back on, as the actress brought Law as her guest to a family function, reports Orange News.
Law and Miller are fuelling rumours of rekindled love after they were seen together on a Caribbean holiday after Christmas.
Miller seems eager to make the reconciliation official, and invited Law to dinner with her sister, Savannah, over the weekend.
The two stars haven’t been seen together publicly since the announcement that they broke off their engagement in 2006. At the time, Miller had learned that Law had an affair with his children’s nanny.
Last September, Law became a father for the fourth time. Samantha Burke, an American model, gave birth to Law’s daughter, Sophia, following their brief romance. Earlier this month, Law agreed to see his new daughter for the first time.
