Is a second proposal on the way? Though Sienna Miller and Jude Law got un-engaged in 2006, a friend of the recently reconciled couple tells Life & Style that Sienna, 28, has been privately wearing her engagement ring among friends. "She wore it for fun, probably as jewelry," says the friend. "But she wore it with close friends, and everyone saw it -- there's no denying it." While the friend says the G.I.

The stars met on the set of 2004's Alfie but broke up after Sienna learned that Jude had an affair with his children's nanny.
