Jennifer Aniston has experienced her fair share of Hollywood personalities over the years - the good and the bad. While sitting down for SiriusXM's The Howard Stern Show on Wednesday, Aniston revealed that one particular male actor who appeared on Friends had an "attitude" while on set. "The funny thing is, that male did apologize about their behavior years later, and just said, 'I was so nervous, to be honest, that I wasn't on my best behavior,'" prefaced Aniston, 52, who joined Friends costars Lisa Kudrow and Courteney Cox virtually.
