Hilary Duff credits all the success of TV Land's dramedy "Younger" to its legendary creator Darren Star.

“Darren Star is amazing," Duff said during interview on GMA Monday morning. "Our whole writing team is amazing, but he just knows how to write for women. All women can relate to it. Woman of all ages. Everybody can relate to wanting to reinvent themselves or feeling a little stuck or feeling someone’s not accepting you."

Star is the mastermind behind iconic TV hits including "Sex and The City," "Beverly Hills, 90210" and "Melrose Place."

"Younger" kicks off Season 4 on June 28 on TV Land, but Duff confirmed that the show has already been picked up for a fifth season.

Duff expressed how "lucky" they all are to be part of the show and said it's a “perfect mix of like tugging at your heartstrings but making you laugh and being a little too edgy. It’s really a tale about friendship. There is love interests weaving in and out, but it’s really a tale about friendship between women.”

When asked if she missed the Disney series that made her a household name, Duff confessed she was happy to move forward from the childhood role of Lizzie McGuire. “I loved it and honestly it prepared me for so much,” the actress reminisced. “I totally related to her loved her, I felt like I was her.”
