JoJo Siwa may have only been dating girlfriend Kylie Prew for five months but she already feels she's changed her life forever.

The 18-year-old YouTube star – who came out earlier this year – had a sweet message for her other half as she marked their five-month anniversary with a sweet post on her social media accounts, calling Kylie "the best girlfriend in the world".

"You've changed my life for forever. I love you more and more every day. Thank you for being the best girlfriend in the world," she wrote.

She added: "Happy 5 months my love bug."

And Kylie posted a sweet message for JoJo, calling the singer and actress her "absolute favourite person".

"I love you more and more each day," she wrote on her Instagram Story.

The couple met on a cruise ship and JoJo was captivated by Kylie when her now-beau quizzed her on who she really was, behind her glittering and successful career.

JoJo recently came out, and later revealed she was in a relationship with Kylie

"I told her my whole spiel that I tell everyone when they ask me my life story."

"She goes, 'I could have Googled that. I want to know your life story. You just told me about your career. I want to know about you.' And I was like, 'No one's ever asked me that before,'" she recalled of their first meeting.

JoJo doesn't like to label her sexuality – but she's so hooked on girlfriend Kylie that if she had to, she'd describe it as "Ky-sexual".

She said: "I still don't know what I am. It's like, I want to figure it out. And I have this joke. Her name is Kylie. And so I say that I'm Ky-sexual. But like, I don't know, bisexual, pansexual, queer, lesbian, gay, straight. I always just say gay because it just kind of covers it or queer because I think the keyword is cool."

"I like queer. Technically I would say that I am pansexual because that's how I have always been my whole life is just like, my human is my human," she added.

JoJo loves how supportive Kylie has been of her

Kylie has been really supportive of JoJo's fame and doesn't worry about what people are saying about them online.

"She never cares what the internet said about us. It's nice to have somebody in my life like that," JoJo shared.
