Olivia Holt wants Reese Witherspoon to be her mother.

The 18-year-old American singer and actress - who made her breakthrough on Disney's 'I Didn't Do It' Original series - has admitted she has long admired the 'Legally Blonde' star and is desperate to play the 40-year-old's on-screen daughter or relative on a film in the future.

Speaking openly to PEOPLE about her ultimate icon, the blonde beauty said: ''I've been a fan of her [Reese] forever. I just want her to be my mom in a movie, or like my cool aunt. One of the two, I'm okay with either/or. I don't even care if she's my mom or my cool aunt. I'll be an extra.''

And the Tennessee-born star has also revealed she admires Chrissy Teigen and regularly finds herself scrolling through America's 'Lip Sync Battle' co-host's social media for culinary inspiration.

Speaking about the mother of one - who gave birth to her two-month old daughter Luna, who she had with her singer songwriter husband John Legend, in April this year - Olivia explained: ''She's funny. She definitely helps when it comes to the food category. I look at her Instagram and I'm like, I'm going to have that.''

Meanwhile the 'Had Me @ Hello' hitmaker can't wait to grace the big stage later this month for her tour, which will start in Salt Lake City on July 15 and draw to a close in California on August 31.

Speaking about her feelings towards her forthcoming gig, she said: ''This is something I've dreamed of since I was a little kid. So I'm just super excited.''
