Quite the gentleman, US rapper Wiz Khalifa has revealed how he has agreed to change his smoking habits while girlfriend Amber Rose is pregnant with his child.

The rapper, who is well known for his love of marijuana and has been arrested for possession twice in 2012 already, has told how he is taking his upcoming parental responsibilities seriously and is now smoking outside.

"I smoke outside instead of inside. Everything is all about smells, man. If the smell irritates her, then it gotta go," he tells MTV news, adding that as well as dictating his smoking habits, Rose will get final say on the baby's name as well.

"We're working on it. You know how difficult that is," he continues, when asked on potential baby names. "But it's all good, though. I let her have her way all the time; that's my baby."

He also reveals that the couple are aware of the baby's gender, but are keeping the news to themselves.
