Sienna Miller has reportedly been wearing her engagement ring again.
The actress - who rekindled her romance with ex-fiance Jude Law last year after they split in 2006 following revelations he had cheated on her with his children's nanny - is said to have donned the piece of jewellery he gave her when he proposed in 2004, and friends believe it is only a matter of time before they get engaged again.
One told Life and Style magazine: "She wore it for fun, probably as jewellery. But she wore it with close friends, and everyone saw it - there's no denying it.
"They aren't engaged yet, but I wouldn't be surprised if she and Jude go all the way. She's very happy."
It was recently claimed Jude was set to propose to Sienna, as he doesn't want to lose her again.
A source said: "Sienna was always the one. And now she is back in his life he never wants to let her go again.
"He needs a good woman to look after him. Sienna's fed up of the single life and wants to be with Jude for good."
Jude and Sienna spent the festive period on the Caribbean island of Barbados together with his three children, Rafferty, Iris and Rudy, from his marriage to Sadie Frost.
Last year, Jude became a father for the fourth time after American model Samantha Burke fell pregnant following a brief relationship.
