The singer, of course, went on to release a few albums with her girl band Bardot, but then shifted her focus primarily on her acting career.
Well, it appears she hasn't lost her voice as she recently caught up with Aria-award winning country singer Kasey Chambers and decided to undertake an acoustic sing-along before the two performed onstage together.
Monk, 37, took to Insta to share the video and captioned it: "She's always had my back! @kaseychambersmusic before we went on stage. One rehearsal ❤️ I messed up 😳 and she still trusted me 😍."
But Monk wasn't the only one to fangirl, 41-year-old Chambers also posted a cute picture alongside the famous blonde.
So cute! Now that we're all nostalgic, check out a video of Monk's solo work.
