Jennie Garth likes a lot of things about Amanda Bynes, but there’s one thing in particular that really stands out for her.

Twenty years after the duo costarred on What I Like About You, the actress recalled how working with Amanda on the hit sitcom helped change her perspective on raising teenage daughters.

“Working with Amanda was eye-opening for me,” Jennie exclusively told E! News in an interview, “because I didn’t know what it was like as the older person to play in the scenes with a younger person, or just to be around that kind of teenage energy.”

As the 54-year-old put it, “She had so much overflowing teenage energy.”

Indeed, Amanda was just 16 years old when the show premiered on The WB in 2002. Meanwhile, Jennie was 30 years old and already mom to daughters Luca Bella Facinelli and Lola Ray Facinelli with then-husband Peter Facinelli. (She later welcomed daughter Fiona Eve Facinelli in 2002, before she and Peter split in 2013.)
