Actress Helen Mirren has some words of advice for troubled stars like Amanda Bynes and Lindsay Lohan, and others who have gone down the wrong path in light of fame.

While promoting Red 2, Mirren offered; “I don't know if you're allowed to say this on television: Don't be up your own bum.”

MSN reports she continued that she just doesn’t understand the culture, saying "People get their own [bum], and you really don't need to. It's the thing of the young, and just don't do that.”

Lohan has been staying out of the public eye in rehab, where she turned 27 this week, but Bynes’ issues seem to just be starting.

Fox News notes Bynes, also 27, has been getting a lot of media attention for her bizarre tweets, and she has a court date next Tuesday in relation to allegedly throwing a bong out of her New York City apartment, which she has since been kicked out of.
