And Kailyn isn't really doing much to squash those rumors. In fact, she's fanning them.
On June 5, the reality star posted a picture with another woman from the Asbury Park Pride festival. In the image, the woman has her arm around Kailyn while Kailyn holds the woman's wrist.
"Girlfriend status 😌 #asburyparkpride @hayter25," she captioned the snap. The other woman in the snap posted the same picture, saying, "Asbury pride with this fine lady."
Granted, Kailyn's simple caption doesn't necessarily mean that the two are in a relationship, but there is social media evidence to suggest that theory. Later in the day, the MTV star shared a snap of her and her "girlfriend" kissing, but she later removed the pic.
Last week, Kailyn posted a photo of her and the mystery gal with the caption "My girl," along with an emoji of a heart and another of two girls holding hands. Around the same time, the woman also shared several intimate images with Kailyn.
One photo shows them with Kailyn's children, Isaac, 6, and Lincoln, 2.
"#familyphoto," she said of the snap.
Another image featured Kailyn and the woman smiling.
"Forbidden fruit," the woman captioned the image of her and the mom of two.
Instagram photos show that the woman -- some reports say her name is Becky, though we're not sure if she likes lemonade -- has been close with Kailyn and her ex Javi Marroquin for quite some time.
Again, the extent of Kailyn's relationship with this woman isn't exactly known. Last month, while revealing that she and Javi were splitting, she said, "We're trying to do the best we can for our kids because they are what really matters."
On the seventh season of the the reality show, the former couple got into many arguments dealing with the aftermath of Kailyn's miscarriage and Javi's deployment.
There have also been rumors that one or both of them cheated.
