I don't doubt it. These celebrities are pleasure seeking little Caligulas. Having all the wealth and power gives them access to a decadent lifestyle once only the available to royal families.
They usually come complete with fake marriages/beards and children.
Guys like Cruise, Travolta, Jackman etc.....the marriages are fronts.
Look at Aaron Rodgers for example. Gay rumors couldn't have been any stronger (broke up with live-in boyfriend) but seems to always have an attractive beard by his side.
People don't want to envision a Leading male movie star, or an All-American quarterback, as being gay.
