But less than a year later, The J Team star shocked her fans after revealing she and Prew called it quits on their relationship in the middle of her Dancing With the Stars stint back in October 2021.
However, many are convinced Siwa has reunited with her old flame, so OK! is taking a look at all of the clues she's dropped so far.
It all started when the Dance Moms alum announced last month that she's off the dating market while speaking on the "Rachel Uncensored" podcast.
"We're not single," Siwa stated on the March 30 episode, per E! News. "I say 'we're' because it's me and my multiple personalities within myself...I am not single and I don't want to mingle. No, I'm a loyal lady."
"Listen, I went around the block," the Nickelodeon star quipped, referring to her phase of dating around. "I tried a lot, and I learned a lot and I'm very, very, very happy where I am now."
While she didn't share who her new (or old) partner is, her fans have all but confirmed Siwa is once again seeing Prew.
The same account posted another clip featuring photos of the "Boomerang" singer cuddled up with Prew on a ride at a Six Flags amusement park.
Users in the comments pointed out the photos must have been taken recently, considering Siwa appears in the snaps with her new haircut after chopping off her long blonde locks earlier this month.
The TikToker also included a photo from the Instagram account of Siwa's friend Ezra, where the rumored pair are seen arm-in-arm in a group photo.
"Congrats you two," the user added.
While neither Siwa nor Prew has confirmed anything about their rumored relationship, her fans already appear to be celebrating their reunion. "I KNEW IT," one user commented, while another stated: "If this is true I'm going to cry. So happy for them!!!!"
