Brittany Murphy claims she is being stalked by a "high-powered Hollywood player", says her former employee.The 'Little Black Book' star also reportedly claimed her husband - British screenwriter Simon Monjack - was kidnapped for 10 days in April by agents of her supposed stalker, according to Brittany's former member of staff.The unnamed male ex-employee told the New York Daily News newspaper: "When he came back, he had head injuries. He was pale and sometimes had trouble standing."The 29-year-old actress then reportedly told the former member of staff she could not pay him because she had used all her money for the ransom. However, the dates of the alleged kidnapping coincide with tabloid reports that Monjack was jailed by US immigration authorities for overstaying his visa. Brittany was rumoured to have married the 'Factory Girl' screenplay writer to stop him being deported from the US. According to reports, Monjack was arrested on expired visa charges in the middle of the night on March 27 - just weeks before the couple's secret wedding. A source told the New York Post newspaper: "Brittany knew nothing about any of that."Monjack's lawyer said: "These charges are being made by disgruntled ex-girlfriends and immigration officials have concluded the marriage had no bearing on my client's visa status."The couple, who began dating last year, tied the knot at their Los Angeles home in front of close family and friends in May. Brittany's representative said: "They were married at their home in Los Angeles several weeks ago in a very intimate ceremony. It was officiated by a rabbi and they were surrounded by their families."The '8 Mile' star insists the deportation rumours are "preposterous lies."Brittany told In Touch Weekly magazine: "Everything was just so fabricated and hurtful."
