Some of Zac Efron‘s fans aren’t age-appropriate. At Nylon Guy magazine’s party for its November issue at XIV in LA, cover boy Efron (pictured) was followed around by a gaggle of women in their 40s. Says a spy, “One of them ended up following him to the bathroom and just waited for him to come out. As soon as he did, she cornered him and asked to take his picture for her 5-year-old daughter. He was very gracious.” Also there was Efron’s “High School Musical” co-star Ashley Tisdale.
