"The conversations have gone on for a couple of years and the timing just didn't seem right and now Lizzie is turning 30,” Duff said. “For me, she was everybody's best friend and she was there for us... entering your 30s is a really big deal."
In the new series, McGuire will be working as an apprentice to an upscale decorator in NYC, but Duff promises the setting will change quickly, representing the busy and unpredictable working lives millennials lead.
"I just thought that there was an opportunity there for her to be grown up and for her to be there for women again," the singer and actress, now a mother of two, added.
Does she have any trepidations about stepping back into a role she left behind 15 years ago? "I'm not gonna lie: I'm a little intimidated. I'm like, 'Where is she in there?' She is in there; she is me. When I was 13, it was such a big part of me... I just have to tap into that and be very authentic to that."
The original show aired 2001-2004, and spawned the successful "The Lizzie McGuire Movie" (2003). The reboot promises to be true to the source material, since Duff is working closely with series creator Terri Minsky.
"I can't wait for her adventures, for her heartbreak, to see her goals and what she's done!"
She — and the rest of us! — will have to wait... the show hasn't even started filming yet.
