According to the Daily Mirror, Salma Hayek is the latest big name to crop up in the saga of the couple's troubled relationship.

Sienna is said to have been furious after hearing that ex-fiance Jude partied the night away in a French nightclub with the Mexican Oscar-nominee.

She is said to have confronted Jude over lunch in the restaurant of his exclusive Paris hotel.

An onlooker said: "It was astonishing. Sienna was screaming as she flew into the room but Jude appeared completely calm and nonchalant... she was clearly very upset."

Jude and Salma were described as "extremely" friendly by other clubbers at Man Ray, the Paris club owned by Johnny Depp and Sean Penn.

Alfie actress Sienna broke off her engagement to Jude, ex-husband of Sadie Frost, earlier this year following revelations of his affair with his children's nanny.

The latest reports have claimed that Sienna had a recent fling with her Layer Cake co-star Daniel Craig, a friend of Jude's and hotly tipped to be the next Bond.

But friends of Sienna claim that Jude and Sienna haven't been a couple since Jude admitted his infidelity.

Of the hotel incident, Sienna's publicist said: "Sienna had arranged to meet Jude in Paris for lunch and it was all very amicable."
