Lacey Chabert isn't worried about ageing.

The 42-year-old actress - who is best known for starring as Gretchen Wieners in the 2004 comedy 'Mean Girls' alongside Lindsay Lohan, Rachel McAdams and Amanda Seyfried - thinks age is "just a number and wants to focus on staying "young at heart" as the years go on.

She told People: "I think age is just a number. Staying young at heart for me is about finding joy in any situation and connecting with people in life. It's part of the reason I think I enjoy being a storyteller and making movies because I love connecting with people through story."

The former 'Family Guy' star has become a mainstay on the Hallmark Channel and regularly appears in television movies for the network but is hopeful that one day she will be reunited with Hollywood actress Jennifer Garner on a project.

She said: "I'm from Mississippi and I haven't gotten to do a movie about the South. I would love to do a southern based movie.

"And I will say the first person that pops into my head for who I would want to work with is Jennifer Garner.

"She and I worked together on Ghost of Girlfriends Past many years ago, and it was such a dream to work with her. She's just so lovely and I love following her on social media."

Lacey played minor roles in US soap opera 'All My Children' and appeared alongside Bette Midler in a television adaptation of the musical 'Gypsy' by the time she was cast as one of the leads in the long-running drama series 'Party of Five' in 1994 but didn't recently explain that she didn't "understand" what it meant to land such a big job at the time.

She told Us Weekly: "I learned so much being on set and really grew up. I went through a lot of firsts, like, kind of every first that a girl from 11 to 17 can go through. And a lot of times [whatever] it was hadn't yet happened for me in real life -- or it was a first time -- and, you know, there was so much reality to it.

"I didn't understand the scope of what it really meant to be on a television show. just knew I loved acting and telling stories, and I got to do that with this incredible group of people who I loved hanging out with!"
