David Hasselhoff's daughter Hayley, 20, has been charged with DUI and could face up to six months in jail.Aspiring actress Hayley, 20 - David's daughter with former wife Pamela Bach - was arrested in Los Angeles in January for DUI and speeding and could face up to six months in jail if found guilty.A source told RadarOnline: "Hayley is going to fight the charges."David has suffered from alcoholism in the past and said it brought him, Hayley and his daughter Taylor-Ann, 22, closer together.The girls released a video of him drunkenly lying on the floor shirtless while trying to eat a cheeseburger in 2007 to make him confront his problems.Â He is grateful to his children for doing that because it made him understand how much they care for him and he claims their actions also helped other youngsters deal with their alcoholic parents.Â He previously said: "I have learned from my mistakes, I have learned from everything.Â "The best part about it [the video] was what it did for my children. So many children called and said that their parents are just like that. They asked, 'What do we do?'Â "It gave my children a great place to say, 'Hey, you just love them, because we love my dad more than anything and it brought us closer to each other.' And in the end it's a video. Who cares, you know? I am still here.Â "In the end a lot of people who saw that video laughed at it, most of the people that saw that video see themselves."
