Taylor Hasselhoff, 32, also opened in an interview with People about how it felt to walk down the aisle with her father.

"I think the reason I started crying is when I saw my dad, because he was just such a big light in my life," she told the outlet, adding that "his smile was so big" that day. "He's also just so supportive and so loving, and I know how much he cares about my wellbeing and my happiness. So it was just an honor to be able to walk down with him and see how happy he was for me to start this new journey."

David Hasselhoff is also father to daughter Hayley Hasselhoff, 30, whom he shares with ex-wife Pamela Bach.
