Sept. 16 (UPI) -- JoJo Siwa says she celebrates four anniversaries with her girlfriend every month.
The 18-year-old dancer and YouTube personality explained on Wednesday's episode of The Tonight Show starring Jimmy Fallon how she and girlfriend Kylie Prew celebrate the anniversaries of four relationship milestones.
Siwa confirmed that she and Prew celebrated the anniversary of Siwa asking Prew to be her girlfriend Tuesday. The couple also celebrate on the 8th, 28th and 29th of each month.
"So, my girlfriend and I -- You know, Ky asked me to be the girlfriend on the 8th. January 8th. But then I was like, 'You know what? I also need to ask you to be my girlfriend.' So we did that. And yesterday was the anniversary of that day," Siwa said.
"We actually celebrate four days, though -- when Ky asked me to be girlfriend, when I asked Ky to be girlfriend, when we told each other that we liked each other, and when we kissed for the first time," she added.
When asked if celebrating four anniversaries is exhausting, Siwa replied, "I mean, we're on month number eight now. And we'll probably stop at a year. I would imagine, every year, we would only celebrate."
On The Tonight Show, Siwa and host Jimmy Fallon also played Fast Dance-Off, a game where the pair took turns making up fast dance moves to the least danceable songs they could find.
Siwa came to fame on the Lifetime reality series Dance Moms. She will compete in Dancing with the Stars Season 30 and become the first contestant to have a same-sex dance partner.
