London: Actor Jessica Biel says she walks out of parties when they get wild and they start becoming drug fests.

"If there is a huge drug fest happening and everyone is getting it on in the bedroom, it is probably time to leave," quoted her as saying.

The 30-year-old is engaged to singer Justin Timberlake and credits her sensible attitude to early working years and family rules.

"I was lucky to get a part in a long-running TV series, `7th Heaven`, when I was 14, and everything took off from there. It was like having two families, my real one and the cast," she said.

"My mum had me under curfew, so I was well known on TV at the same time as having to be back home early," she added.
