2/15/2007 in Actor is dumped by girlfriend, has sexual escapade with stewardess. Jeannine Coppola According to the Daily Mail, actor Ralph Fiennes was dumped by his girlfriend of five months, Sirin Lewenden, only a few days before rumors surfaced that he had an sexual encounter with a flight attendant in an airplane toilet. Lewenden, who is an interior designer from Dublin, called Fiennes "sex obsessed" and said she was sick of the Oscar-nominated star's "wandering eye", "moodiness" and "constant demands for sex." The amourous affair happened on Fiennes's long flight from Darwin, Australia to Mumbai, India. Quantas stewardess since 2004, Lisa Robertson, 38, has been hiding since the incident occurred on January 24, 2007, when the plane was apparently seven miles high. However, when pictures of her emerged on the Internet portraying her as a homely girl with blonde highlights, her father, Graham, defended her. He stated, "Lisa just does her job and if someone wants a cup of coffee and biscuits, she looks after them...She"s not a bad-looking girl. If you do the right thing people take a liking to you." He also added that she was a "good kid" and that Lisa's Qantas colleagues who saw her emerge from the same toilet as Fiennes were "probably ugly as a hat full of a\*\*\*holes and were just jealous." In a signed statement to the airline, Lisa states taht she started talking to Fiennes when he sat next to her in a crew jump seat during the flight, confirming that "This is common practice on long flights to build a rapport with passengers and converse with them during the flight. She then told The Star that when she went to use the bathroom, the actor followed her and began to make sexual advances toward her. Once they were locked in, she says she tried to resist his actions, claiming, "I explained to him that this was inappropriate and asked him to leave." Fiennes, 44, has been described as an immature petulant child by Lewenden's girlfriends, who admitted that "Sexually, he was also very adventurous. Initially, Sirin thought it was all apart and parcel of the first throes of romance. She had hoped it would all calm down a bit, but it didn't and it just didn't do it for her after a while. They sum up the reasons for the Sirin and Fienne's break-up, ""They split because of Ralph's wandering eye and his constant demands for what might best be described as unconventional sex. He could also be prone to the odd mood swing." Lisa Robertson, who is from Sydney,is currently suspended without pay until the outcome of the investigation. Fiennes, who starred in "Harry Potter And The Order of the Phoenix", "The English Patient", and "Schindler's List", divorced his wife, Alex Kingston in 1997 after four years of marriage. He also had a known romance with Francesca Annis, his partner in a London Theatre production of Hamlet who was 18 years older than him, in 1995. They separated in 2006 after there were reports that he had an affair with a Romanian singer. He then got together with 42-year-old Lewenden.
