Urinating in a janitor's mop bucket, spitting at fans and most recently allegedly getting into a bloody brawl in the upscale area of The Hamptons, it appears the 19-year-old is becoming more and more out of control.
Now the teenager's mother Pattie Mallette has now opened up about her son's actions in an interview with Extra host Mario Lopez.

Mallette says that when she does speak to her son, she makes sure that she gets her feelings on certain issues across to him.
'We talk about the things that he is going through. We talk about the pressures that he is under and what people are saying and how he feels about it and the questionable things that people are saying that he is doing,' she explained.
'And we talk and he knows what I think...I definitely am a mom first and I care deeply about what how he is feeling and what he is going through.'
