Sienna Miller alone at a pre-Bafta partySienna Miller alone at a pre-Bafta partyJude Law and Sienna Miller won't be getting married for at least another year - because they don't want to steal their siblings' thunder.

The couple got engaged on Christmas Day after meeting on the set of Alfie, and were expected to tie the knot this summer.

But Sienna, 23, told reporters at a pre-Bafta party she was in "no rush" to be Mrs Law - unlike thousands of others.

"I'm not getting married this year; I would say if I was," she insisted, flashing her chunky diamond engagement ring.

"My sister and Jude's sister are both getting married this year. There's no rush, we're just happy to be engaged."

Jude wasn't with his fiancee because he's in the States filming All The King's Men.

But Sienna told the News Of The World he was "lovely, lovely, lovely".

"It still feels like a whirlwind romance because I still can't believe what's happening to me. I'm the luckiest woman alive."

Sienna accepted a clutch of diamonds as the best breakthrough actress at the party - an award won last year by Scarlett Johansson and probably a bit more valuable in real terms than a Bafta.
