Sienna Miller wants Ifans to 'tone up'

Sienna Miller has allegedly told fiancé Rhys Ifans to get in shape before they marry.

The couple are thought to be planning to wed in the summer and Miller is eager for Ifans to "tone up".

The Mirror quotes a source as saying: "Poor old Rhys must find it hard to measure up to her exes. He's always been quite skinny. Sienna loves him but she just wants him to tone up a bit so he looks great for their big day."

The actress has reportedly bought Ifans a Power Plate exercise machine to start his fitness regime.

"Rhys received the Power Plate a couple of days ago and he's been using it already. He's determined to do whatever he can to make Sienna happy," the source added.

"Sienna is filming in LA at the moment and she's left Rhys home alone with instructions to get some exercise. She has been in training for the movie GI Joe, so she thinks they should both be keeping fit."
