Paul McCartney must have been a huge aphrodisiac for Ronnie Wood. The Rolling Stone, who’s 63, was spotted canoodling with new Brazilian-born girlfriend Ana Araujo, 30, during the former Beatle’s concert at the Apollo Monday night. A spy told us, “Ana was rubbing his leg and they were kissing so much through the concert. He looked great but was chain-smoking so much before that he stunk like a cigarette.” Wood, who was also spotted doing tequila shots before the show, joined fellow stars including Ben Stiller, Val Kilmer, Paul Simon, Chris Rock, Martha Stewart and Howard Stern.
