Also on Friday, Alicia delved into her new Netflix series The Baby-Sitters Club.

‘I really appreciate that we have a strong female lead,’ she told People, referring to Sophie Grace as Kristy Thomas.

‘She’s feisty, and it’s about female empowerment. This entire show shows children having really loving, thoughtful friendships.’

In the kid-friendly series, a group of middle schooler girls join forces to handle baby-sitting duty and find a vintage 1990s landline phone to take calls.

The series is based on the best-selling book series of the same name, and was preceded by a 1990 series and a film from 1995.

‘This entire show shows children in a way that I don’t think we were like when we were that age in school,’ Alicia continued. ‘These kids are kind and evolved.’

The show also got high praise of her son Bear.

‘He wasn’t like, “Wow Mommy, I’m watching a show about girls.” He just loved the characters,’ she said.

The actress, who’s best known for her role as Cher Horowitz in 1995’s Clueless, is often accompanied by Bear on her outings, though he sat out Friday’s hike.

Last month, she caused a stir when she opened up about her bathing habits with her nine-year-old son in The New York Times

‘My son and I take baths together,’ she said of Bear, adding that when he’s not around, she takes ‘a bath and that really feels nourishing and comforting.’

She shares her son with the musician Christopher Jarecki, whom she was married to from 2005–2018.
