In one shot, she copied her mum’s look from the 1996 music video Say You’ll Be There, with a leopard print corset top, black skirt and fingerless gloves.
In other scenes, she recreated the outfit her mum wore on the 1997 Spice Up Your Life album cover and the two-piece set she donned in the Spice World movie poster.
"Loved this outfit from a photoshoot mum did in 1997," Phoenix captioned one of the videos.
Fans quickly flooded her videos with messages of support, sharing that they loved the nostalgic TikToks.
"I am LIVING for these!! I still listen to the Spice Girls every day! Thank you for the nostalgia." wrote one fan.
Another commented, "Omgosh you are bringing me back you recreating your mom is everything right now."
"I AM NOT THIS GOD DAMN OLD!!!! But mini scary spice. You killed this like omg!!! Nostalgia x100," wrote a third.
While some fans may have thought Phoneix's recreation was the closest they would get to a Scary Spice comeback, Mel surprised fans for the teaser of the upcoming season of The Masked Singer Australia, with the judge recreating her iconic leopard print look.
"Yippeee no one had to twist my arm for a "90s dress up" for @themaskedsingerau but it meant I had to dig into my wardrobe and bring out this look from the 1998 tour," she wrote to Instagram.
Fans were ecstatic to see the full 90s look back in the limelight, with many sharing their excitement on social media.
"Wow! You look exactly like you went back in time! Looking stunning!" wrote one fan.
"Get your move on with the tour hun. I can't wait no longer. Need Spice back in my life xx," added another.
In early 2023, the duo also posed together for Pour Moi's Own Your Confidence campaign alongside Mel B's mother Andrea.
"It's time we owned our confidence, spread those positive vibes, and empower others to be their true selves! I had so much fun shooting this with my daughter Phoenix and mum Andrea, showing you how you can feel confident, comfortable, and fabulous," Mel B wrote to Instagram.
