“Teen Mom 2” star Kailyn Lowry has been comparatively mum about her fluid sexuality, but fans may be getting the lowdown on it soon. She will spill the beans in her new tell-all book, “Hustle & Heart,” which will hit bookshelves in the fall.

“People can read my book if there’s anything they want to know,” Kailyn, 24, told Radar Online in an exclusive interview about the rumors. “‘Hustle & Heart’ should be out this fall.”

Gossip began after Kailyn posted online a photograph of herself kissing longtime friend Becky Hayter at a gay pride celebration in Asbury Park, New Jersey, Sunday. The “Teen Mom 2” star soon deleted the evidence, but then she posted a photo of herself and Becky on Instagram. She fueled the rumors when she captioned the picture, “Girlfriend status.”

While fans may be shocked about Kailyn being in a same-sex relationship, it’s nothing new among her friends. “Kail was with a girl named Shelby for about two years,” a source told Star magazine in 2012.

It was a middle-school relationship. “Jo [Rivera, the father of her older son] knew about Kail’s relationship with that girl. He thought it was a phase,” the source said.

Kailyn would neither confirm nor deny the relationship on Twitter. “Do I have to be gay or straight? Can’t I just love people?” she wrote Tuesday. “What’s meant for you won’t miss you."

Kailyn and estranged husband Javi Marroquin announced their divorce last week after almost four years of marriage. Javi didn’t want to continue their marriage after Kailyn decided she didn’t want to have more children with him. “I’m always gonna resent you, I’m always be mad at you deep down ... Once we decide to get a divorce here, or when we decide to get a divorce when I get home, my dad can move my s---, and when I get home I don’t have to go to that house,” he said in the “Teen Mom 2” Season 7 finale Monday.
