JoJo Siwa praised her girlfriend, who recently encouraged her to come out, and revealed glimpses of their relationship via Instagram on Monday (Feb. 8) to celebrate their one-month anniversary.

The teen superstar showed off the good times she's spent with her girlfriend Kylie, from wearing fuzzy Grinch-themed onesies to singing Justin Bieber's "As Long as You Love Me" in the car.

"After being my best friend for over a year, January 8th 2021 I got to start calling this exceptional human my Girlfriend... and Since then I’ve been the happiest I have ever been!" Siwa captioned the series of posts. "She seriously is the most loving, supportive, happiest, protective, and just the most beautiful perfect person in the world. And I get to call her mine! Happy one month to my girl! I love you more and more everyday!"

The Nickelodeon star announced she was part of the LGBTQ+ community on Jan. 22 when she posted a now-viral picture on Twitter of a new T-shirt her cousin gifted her that read, "Best. Gay. Cousin. Ever." Earlier that month, she posted a TikTok video of her lip-syncing Lady Gaga's "Born This Way" and received lots of love and support from fellow TikTok stars and friends.

Siwa opened up about her coming-out journey on The Tonight Show Starring Jimmy Fallon last week and how Kylie helped her take the first step by posting the picture of her "Best. Gay. Cousin. Ever." tee to her millions of fans.

"One day, I was on FaceTime with my girlfriend.... And we were both like, 'Technically, I still haven't confirmed it.' And so I was like, 'I kinda just want to post this picture on my real story.' And she was super encouraging, she was like, 'Do it!'" Siwa recalled in her late-night TV interview. "And I was like, 'All right!' And I did it!"
