The 65-year-old "Money Can't Buy You Love" singer, who has recently romanced married millionairess Nancy Shevell and actress Rosanna Arquette, has been described as "predictable" when it comes to seducing the opposite sex.
A source told the New York Post newspaper: "He has a ritual. He buys the same thing."
"He's been buying a bottle of perfume and lingerie for so long, it's predictable. He gives it to them even before they get dinner. He's done it with everyone he's been with."
Since the former Beatle split from Heather Mills - with whom he has a four-year-old daughter Beatrice - in 2006 he has been linked to a series of women including "Bridget Jones" star Renee Zellweger.
McCartney met his first wife Linda - who died of breast cancer in 1998 - in New York in 1968.
Before that he dated British actress-turned-cook Jane Asher who he met after a Beatles concert at the Royal Albert Hall in 1963.
