SIENNA MILLER’S dad has warned her wandering fella JUDE LAW he will kill him if he cheats on his daughter again.
The threat emerged as Sienna talked for the first time about her man’s infidelity, admitting: “If you are in love with someone, you stay with them regardless of what happens.”
The actress and Jude were with her family at a dinner in New York to celebrate the premiere of her movie Casanova.
Mr Miller explained how Sienna took Jude back after he did some serious soul searching.
He added: “He did a lot of hard work, trying to figure out who he was.
“And I told him if he did anything like this again, I’d kill him.”
Sienna said Jude was “just too close to cut out of my life, he’s my best friend.”
She said she was delighted they had patched things up after he admitted cheating with his children’s nanny, Daisy Wright, in July. Sienna added: “I’m part of a huge majority of people that have experienced infidelity in a relationship.
“I’m not the first person and I won’t be the last.
“He is just too close to me to cut out of my life.
“If you love someone and they are your best friend and you have a giggle it is worth saving.”
Sienna was distraught when Jude admitted sleeping with Daisy.
She called off their planned wedding and was later linked to new James Bond star DANIEL CRAIG.
But Jude and Sienna, who met on the set of the movie Alfie, reunited last month after spending nearly a week locked away at a romantic hotel in Santa Monica, California.
Another guest at the dinner who spoke to Jude said: “He very earnestly and sincerely told me it’s been a hell of a year.
“But it’s over now, he said, or rather insisted. I believe him.
“After Christmas with his three kids he said he and Sienna will head to their house in the English countryside to quietly see in the New Year.” Sienna plays Francesca in Casanova, which co-stars HEATH LEDGER.
She said the historical outfits she wore for filming were painful but gave her boobs for the first time.
She explained: “I loved the cleavage. I never realised I had breasts until I started working on this movie. I was thrilled.
“The corsets look fantastic although they are agony — they squeeze you within an inch of your life.”
