Texan model Jerry Hall, who recently separated from Rolling Stones singer Mick Jagger, is now believed to be linked with Paul Allen, the billionaire co-founder of Microsoft, reports Britain's Daily Telegraph. Friends of Hall, 43, say she has been vacationing on one of Allen's yachts in the south of France. Allen, 45, is said to be worth $22 billion. "Jerry has definitely been around Paul recently. She is one of the people who has been on his boat," a source told the Telegraph.
