COURTNEY Love tweeted after performing Sunday at Carnegie Hall alongside Bono and Gavin Friday: “I have kissed a lot of rock stars in my time but seriously never so many as the last 24 hours.” Love wrapped her legs around Friday — a childhood pal of the U2 frontman — and covered him with kisses onstage. Insatiable Love was also seen grabbing Bono, The Edge and Scarlett Johansson backstage for a kiss. No word if she also managed to get her hands on Lady Gaga, who brought the house down in a skimpy leotard with matching pasties.
