Sabrina Carpenter's “Girl Meets World ”Costars Celebrate Her Smash Hit 'Espresso' in Cute TikTok: 'Fans Since 2013'

August Maturo and Ava Kolker starred alongside Carpenter in the Disney Channel series from 2014 to 2017

The Girl Meets World cast still rides for Sabrina Carpenter!

Amid Carpenter's record-breaking streak with “Espresso” and "Please Please Please," two of her former costars are making it clear that they're not bandwagon fans — they've been here for a while.

August Maturo and Ava Kolker, who starred as Auggie Matthews and Ava Morgenstern, respectively, on the Disney Channel series, made a joint TikTok on July 1 as they pointed out just how far back their support of Carpenter, 25, goes.

"How you guys know Sabrina vs. how we know Sabrina," Maturo, 16, wrote over the video, as he and Kolker, 17, sang along to "Espresso" before a photo of each of them on Girl Meets World with Carpenter flashed on the screen.

In the first photo, Carpenter, who played Maya Hart, held Maturo by the robe as she looked down angrily at him. Her character was best friends with Maturo's older sister, Riley Matthews (Rowan Blanchard), and the son of Boy Meets World's Cory (Ben Savage) and Topanga (Danielle Fishel).

In the second photo, Carpenter and Blanchard stood on either side of Kolker, who played Maturo's girlfriend.

"We’ve been fans since 2013 ya’ll [sic] are just catching up," Maturo wrote in the post's caption.

In the nearly three months since "Espresso" was released, Carpenter has been scoring several major career highs — including her first-ever Billboard Hot 100 slot — and another one of her Girl Meets World costars has also been by her side for it all: Danielle Fishel.

Fishel, 43, praised Carpenter, who played her onscreen daughter's best friend, in a post on her Instagram Stories after her song hit the No. 7 spot on the chart.

"You've done it my bb!! I'm crying fr," she wrote over a screenshot of the Billboard chart, along with a "Congratulations" sticker.

Fishel was also there to support the singer as she made her debut as a musical guest on Saturday Night Live during its season finale 49 in May.

"Had the literal time of my life watching my bb check a massive box off her bucket list," she wrote in an Instagram post as she shared photos from SNL — including a sweet shot of her and Carpenter hugging. "Met some absolute legends and cried tears of joy. NY, you are magical!"

“I love you!!!!!” the singer commented on the post, which also featured a selfie with Fishel and Corey Fogelmanis, who starred as Farkle Minkle on Girl Meets World, which aired from 2014 to 2017 for three seasons.

In 2015, Carpenter told PEOPLE that the cast of the reboot had blended seamlessly with the OG cast, as Fishel, Savage and Rider Strong had all reprised their roles.

"It's like we're all family now. I think that was so miraculous to me, when we started this show. It's hard to come into a family that's been together for seven seasons, and they welcomed us like we'd been with them forever," she said at the time. "It's one of the most amazing experiences of my life."
