Do you remember how you met every one of your friends? Singer-turned-actress Mandy Moore and dancer-turned-actress Jenna Dewan, who鈥檝e been friends for almost two decades, have a little known single from Moore鈥檚 first album to thank for their initial meeting.

During an appearance on Monday night鈥檚 The Late Late Show With James Corden, the This Is Us star explained how she first connected with the future Step Up star. 鈥淚t was a song called 鈥楽o Real鈥 that was like a single in Australia or something,鈥 Moore recalled. 鈥淏ut Jenna, obviously, is the most amazing dancer, and she was a dancer in the video!鈥

Dewan explained that for her, starring in a Mandy Moore video was the hugest deal in the world at the time. 鈥淚 called my family,鈥 she told Corden. 鈥淚 was like, 鈥業鈥檓 doing a Mandy Moore video.鈥 It was this huge production. I was just overly excited.鈥

The video shows Moore writing in her journal in a field during the day before switching to a magical night scene complete with very 鈥90s hair and makeup and a set of backup dancers. Dewan鈥檚 appearance is brief, but she gave the performance her all 鈥 which may have been too much. 鈥淚 danced way too hard the entire time,鈥 she joked.

Of course, Moore isn鈥檛 the only celeb that 37-year-old Dewan danced with back in the day. A few years after her 鈥淪o Real鈥 encounter, she performed with legend Janet Jackson in a moment she got to recreate earlier this year at the Hollywood Bowl.

鈥淪he asked all of her, what she calls 鈥榣egacy dancers,鈥 all of her old dancers to come back and do 鈥Rhythm Nation,鈥樷 Dewan explained. 鈥淚t鈥檚 like the best high school reunion.鈥

Speaking of high school, Corden pointed out that both Dewan and Moore were cheerleaders when they were younger. Naturally, he had some throwback photos on hand 鈥 which inspired Moore to get up and demonstrate one of her old routines. Watch the video below, and see Corden attempt some of Janet Jackson鈥檚 moves in the clip above!
