When Russell Brand was at his most promiscuous when he was drinking and taking drugs flirting outrageously with all
the ladies and portraying himself as the dandy seducer, in his MTV days. It would have been very easy to make a pass
at someone either verbally or by body language or through touch who didn't want his advances. Or who enjoyed the
experience at the time but regretted it later when they were sober.
In fact, there are endless clips of him flirting with women on youtube of all ages and most of the women are going along with him
and having fun, but all it takes is to do this with someone who maybe is a lesbian, or deeply religious in a committed relationship
and the problems can then start.
It has happened in the past to Mick Hucknall, who was very promiscuous when he became famous, and also very forward
when he met the ladies. When he falsely got rape allegations made against him.
