Zac Efron was horrified when he was spotted at a sex shop in New York.

The 'High School Musical' actor was filming the movie 'Are We Officially Dating' at Fantasy World' in the city and was mortified when a paparazzo took pictures of him in the adult store surrounded by x-rated toys.

A source told the New York Post's Page Six: ''Zac was begging the guy to delete the pictures. He kept telling him that he has so many young fans and he didn't want them to see it.

''The photographer refused, so his reps were quick to announce the news that it was simply a scene for the upcoming romantic comedy.''

Recently, Charlie Sheen drunkenly gave a baseball worth $2.6 million to Zac.

The 'Major League' star discovered his prized sporting item - signed by baseball legend Babe Ruth, who died in 1948 aged 53 - was missing from his collection and eventually remembered he had given it away to his 25-year-old pal after a night out. As Charlie had been drunk he initially couldn't remember giving the unique piece of memorabilia to Zac.

A source said: ''Charlie is a baseball fan. He is really proud of the array of stuff, old and new, that he has amassed and keeps it in a special room in his Los Angeles mansion.

''One evening he and Zac had been having a wild boys' night at Charlie's. Charlie showed him his collection and Zac was blown away by the 1920s signed Babe Ruth baseball which he'd bought at auction for $2.6 million.

''Charlie got it out and suddenly told him it was all his, that Zac could keep it.''
