Ashley Tisdale `likes darker, bad boy type guys`

Washington: Ashley Tisdale definitely knows what she likes, and that is "dark and bad boy type of guy".

According to a source, her musician fiancé Christopher French falls in to that criteria and that is why she is attracted to him, it has been revealed.

The source told Us Magazine that even though, the former ` High School Musical ` star`s soon-to-be husband is a bit edgy, he is still a gentleman, as he holds out her chair for her, holds the door among other things, which is why they gel together so well.

The couple recently got engaged on the 103rd floor of the Empire State building.
