"‘She is perceived as nothing more than a home-wrecker. It would be different if her movies did big numbers at the box office, but they don’t."
Sienna Miller is said to be ‘devastated’ after her married lover ran home to his wife and four children.
Sienna, 26, has been furiously calling and texting oil fortune heir Balthazar Getty after learning he had returned to Los Angeles to attempt a reconciliation with his wife, Rosetta.
A source said: ‘Sienna and Balthazar were in New York for a few days together and then he told her he was going to LA to work and see his kids. But the reality is he is desperately trying to get back with his wife.
‘He realises he’s made a terrible mistake. He is trying to keep Sienna at arm’s length and hasn’t told her it is over yet so she is going frantic.
‘She has been calling and texting him constantly and is planning to go to LA herself as she believes she can win him back if they have a face-to-face meeting.
'She’s devastated that he has distanced himself from her both emotionally and geographically.’
The couple had met up in New York after being spotted frolicking at a beach on Italy’s Amalfi Coast two weeks ago. Sienna was photographed topless in Getty’s arms.
Yesterday, he appeared flustered when approached at his £1.5million marital home in the Hollywood Hills, saying only: ‘I can’t comment. When I’m ready, I’ll issue a statement. It’s because of the children.’
According to a producer friend of 33-year-old Getty – a former drug addict and alcoholic who is receiving counselling – he has definitely dropped Sienna.
The producer said: ‘Balthazar and Sienna seemed infatuated with each other when they were in New York last week but I heard the reason the whole Sienna fling happened was because he fell off the wagon.
‘As soon as Balthy arrived back in LA on Monday he started pleading with his wife to take him back. He told me he’d gone to their house but she wouldn’t let him in. He stood outside crying.’
The producer said: ‘He came back to a hotel and was on the phone to Rosetta on and off for two hours, crying and constantly calling and she finally agreed to let him back in the house.
'In his mind he has definitely dropped Sienna but he’s in a very confused state at the moment. His biggest fear is losing his kids.’
Other friends also claim that Getty, who is heir to a £2.5billion oil fortune, became infatuated by Sienna after falling off the wagon.
One of them said: ‘He stopped ringing his counsellor and stopped going to meetings. Rosetta is convinced that him not being sober is the key to the whole mess with Sienna.
‘She is saying the only way she will take him back is if he agrees to addiction and marriage guidance counselling. He humiliated her but he is still the father of her four children.’
Actress Sienna, who dated Jude Law while he was still married to Sadie Frost and then dumped Rhys Ifans for Getty, has been confiding in her mother Jo, a drama teacher.
A London-based friend said: ‘Sienna has been on the phone to her mother in tears asking her for advice. Jo knows Balthazar as she was with them in Italy.
'Jo has been telling Sienna to give Balthazar space. But Sienna is worried if she gives him too much space she will lose him. She already knows he is drifting away.
If she knew he was at the house with his wife she would not like it at all.’
A spokeswoman for Sienna refused to comment.
She is rumoured to have flown from New York to the Caribbean last Monday, the same day her married boyfriend returned to Los Angeles.
The source said: ‘She is planning to fly to LA to see Balthy. She has no idea he is at the wife’s house. He told her he was going to see the kids.’
The scandal has left Sienna’s reputation in Hollywood in tatters. She has already attracted the nicknames ‘Sluttyenna’ and ‘Serial Miller’ because of her numerous high-profile affairs.
A public relations executive told The Mail on Sunday: ‘Sienna’s reputation in Hollywood has gone from bad to worse.
‘People didn’t like it when she was running around with Jude Law while he was still married but this whole thing with Getty is the pits.
‘She is perceived as nothing more than a home-wrecker. It would be different if her movies did big numbers at the box office, but they don’t.
'It’s one thing to misbehave in private but when you cause a huge public scandal and then are photographed half naked with someone else’s husband, that is something that not only destroys marriages but it can also destroy careers.
'Sienna is on very thin ice. Rosetta is hugely popular.’
Rosetta, 38, who runs her own fashion house, counts Demi Moore, Courteney Cox and Patricia Arquette as her closest friends. The Gettys’ children are Cassius, eight, Grace, seven, Violet, four, and ten-month-old June.
Rosetta declined to comment last night on a possible reconciliation.
Meanwhile Sienna's jilted ex Rhys Ifans spent the last week trying to get over his heartbreak with a series of boozy nights out - with a string of beauties.
The 40-year-old Notting Hill actor was spotted out with friends - and a pretty female companion - just a day after he enjoyed the latest in a series of dates with Rod Stewart's daughter Kimberly.
Ifans was said to be devastated at his split with Sienna, who rubbed salt in the wounds by recently claiming their relationship was 'never that serious'.
