Reese Witherspoon's estranged husband Ryan Phillippe has sparked rumours he is dating 18-year-old actress Nikki Reed after the two were spotted leaving a Hollywood club together. Witherspoon and Phillippe, who announced they were splitting in October (06) after seven years of marriage, have two children, AVA, seven and DEACON, three. Phillippe, 32, took Reed to new Hollywood hotspot Winston's Monday night (05FEB07) and they were later seen speeding off in his car. Reed made her film debut in the movie THIRTEEN, which was written by Reed and the movie's director CATHERINE HARWICKE, and was partially based on her rebellious life as a young teen. The FLAGS OF OUR FATHERS star recently denied rumours that his partying and flirting destroyed his marriage saying, "I'm not a perfect person. (But) I'm not guilty of a lot of things I have been accused of."
