Apparently, Rhys Ifans has gotten fed up with the low-profile relationship that he has with Sienna Miller. He has issued an ultimatum to the Factory Girl star, “marry me, or it’s over” during a recent trip to New York.

He wants them to go public with their engagement, but for Sienna, the ring remains in the box. Sources say that Rhys is fed up with all of the secrecy surrounding their relationship and wants to make it a permanent thing.

“He has asked Sienna to marry him and it’s the last time he will ask. He wants everyone to know they are officially an item.”

Reportedly, Sienna has yet to make a decision and Rhys can’t understand why. Is she holding out for a better offer?

He’s no Jude Law, that’s for sure.
