Sienna Miller and Rhys IfansSienna Miller has reportedly told fiance Rhys Ifans to shape up before their wedding.

The pair are said to be planning to marry in a low-key ceremony this summer but Sienna thinks there is still time for Rhys to tone up before then.

A source told the Mirror that she’s had a £3500 exercise machine delivered to their Notting Hill home so he can work out while she’s filming GI Joe in Los Angeles: “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, so she thinks they should both be keeping fit.”

“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.”
