Sienna sparks engagement rumours...

IS Sienna Miller dropping a heavy hint to her boyfriend?

The actress, who has been engaged twice before — to actors Jude Law and Tom Sturridge — was snapped sporting a large diamond ring on her engagement finger on Wednesday night, prompting speculation she had notched up another fiance.

Miller, 35, has been dating 50-yearold film director Bennett Miller for a year, after they met on the set of Foxcatcher. However, Miller claims it was ‘a silly mistake’ and she had merely forgotten to take off her prop ‘Mistake’: Sienna sporting sparkler, inset, this week.

At least Sienna won’t need to change her name if the couple ever do tie the knot . . .
