Recently, sources claimed that the 'Brave Heart' star has been drinking cocktail, and that he appeared to be high during one of his night outs in Bali.
However, Gibson's publicist Alan Nierob also said that people should not assume things so quickly.
"People should not be so quick to assume things," News.com.au quoted the publicist, as saying.
"Unless he (Gibson) is there drinking water, coffee, tea or soft drinks, they're hawking misleading photos," he added.
A business partner, who doesn't want to be named, also said that the actor is just drinking non-alcoholic drinks.
"He was in Bali and he was not drinking alcohol," the source said.
"He was drinking those non-alcoholic virgin cocktails that are made in those island resorts,' the source added.
