Rumors that Scott Disick and Kylie Jenner are dating have swirled after Jenner, 17, posted a poolside picture to Instagram two weeks ago. Disick, 31, has dated Kourtney Kardashian for seven years and has three kids with her, and that hasn't stopped the rumor mill from churning. Disick also has been tied to Kendall Jenner.

“Pool day @ the Disick mansion,” Jenner, captioned the photo. More than 1 million of her 20.3 million followers like the March 29 image.

Even though Disick might have “no boundaries” with the Jenner sisters, the Kardashian-Jenner-Disick clan could have posted the scandalous picture just for the attention. “This is getting to be a joke between all of them now,” a source told Hollywood Life Thursday. “Scott’s joking that he has a harem and he thinks it’s hilarious. Kylie and Khloe [Kardashian] make jokes about it, too.”

Though Kylie Jenner and Disick’s relationship is all laughs, there are claims that he and Kendall Jenner are having a fling. The cover of Star magazine read she was pregnant with his baby. Meanwhile, Kendall isn’t the only one who has battled pregnancy rumors. Kylie is also allegedly expecting a baby — not with Disick, but with her 25-year-old “friend” Tyga. Kylie and Tyga have never confirmed their relationship officially, but it’s widely assumed the two are dating.

“The idea of having [Tyga’s] baby only made Kylie feel more attached to him,” a different source told Life & Style, via Hollywood Life. “Kylie is insisting on keeping it.”

Kylie has not addressed any of the rumors. The last time she posted on Twitter, she promoted the family reality show “Keeping Up With the Kardashians,” which airs every Sunday on E! at 9 p.m. EDT. Some of the sisters are currently in Armenia, where they are commemorating the 100-year anniversary of the Armenian genocide.
