On Thursday's "Joy Behar Show," Rod Stewart opened up about his biological daughter who was put up for adoption. “She was put up for adoption when I was 17 or 18,” Stewart told Behar of Sarah Streeter. “I was absolutely stone broke and didn’t have a pot to piss in… and so she was put up for adoption.”Street is now 46, and didn't learn that Stewart was her biological father until she was an adult.”[She] found out who her father was about 15 years ago, but she still had her mother and father who looked after her so I didn’t want to get involved and upset the apple cart,” Stewart said.Streeter's adoptive parents have both passed away, and now she and Stewart and becoming closer. “Since her mum and dad have died, obviously I’m the biological father, we’ve tried to come together and be close together,” Stewart said. “It’s working out pretty well.” Stewart also cleared up what happened when his son Sean was arrested earlier in the week. “Let me clear up my son’s problem,” he said. “It was all a big mistake, they thought his license had run out, it hadn’t so they let him go.” You can watch a clip of the interview here.
