While promoting her debut children's book, A Kids Book About Periods, the actress participated in PEOPLE's Kids Interview and was asked by kids about everything from her skincare routine to her favorite dress that she's worn this year. When asked about her favorite part about being a boy mom, she shared a sweet answer. “Hi, Miss Jessica! I’m Kai, I’m 5. What’s the best thing about being a boy mom?” the little boy asked Biel in the video. “Oh my God, Kai! You’re adorable. I have a 9-year-old son and a 3-year-old son. The best thing about being a boy mom is playing," Biel responded. "I think playing with my sons is the most fun. Wrestling, playing LEGO, building LEGO, swimming, playing sports, reading together. I love spending time with them, and I love getting down and dirty with them on the floor and just having fun. Not worrying about getting dirty or anything like that. I love that about being a boy mom." Close
