Sienna Miller Coy Over Marriage Ultimatum

Sienna Miller has been issued a ‘marry-me-or-else’ ultimatum from her boyfriend Rhys Ifans.

Ifans proposed to fellow actor Sienna on a recent romantic trip to New York - hoping to announce the engagement upon their return to Britain.

However, things didn’t go exactly as he planned.

“Rhys is fed up with all the secrecy around their relationship and wants to make it a permanent thing," a source tells The Mail.

"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."

"Sienna has yet to make a decision and Rhys can't understand why.

"Sienna's always trying to avoid the official relationship topic and is happy to keep it a low-profile affair.”
