DNA tests disclosed Wednesday morning in London have proved that Hollywood producer and real-estate scion Steve Bing, 37, is the father of Elizabeth Hurley’s baby son, Damian, according to Bing’s spokeswoman, Sue Stapely, and reported by the Associated Press. “Recently conducted tests have shown that Steve Bing is the biological father of Elizabeth Hurley’s son, Damian Charles Hurley,” Stapely said in a statement. The results of the medical tests were revealed at a hearing in the Family Division of the High Court in London, ending months of speculation and accusations on both sides of the Atlantic as to who might have fathered the boy, who was born April 4. At the time of the court announcement, Bing was in the United States and did not immediately issue a statement. Hurley, who turned 37 on Monday, had insisted from the time she became pregnant that Bing was the one and only man who could have been the child’s father. Bing has long contested Hurley’s claim and, as PEOPLE.com reported last month, is also being cited in a spousal- and child-support case as allegedly being the actual father of billionaire Kirk Kerkorian’s 4-year-old daughter by estranged wife Lisa Bonder Kerkorian, 37. Kerkorian, who is 84, claims to be sterile. Bing is denying that claim and is suing Kerkorian for more than $1 billion for invading his privacy when reps for the billionaire allegedly searched through Bing’s garbage to locate dental floss that could be used in DNA testing. So far, there has been no statement from Hurley.
