Looks like there’s already trouble in paradise for Khloé Kardashian and Tristan Thompson.

Sources close to the new couple exclusively tell In Touch that the Keeping Up With the Kardashians star is involved in a cheating scandal — as the Cleveland Cavs center, 25, was with his pregnant girlfriend Jordan when he met the reality star, 32.

With one source saying that Tristan is now “out of the picture” despite Jordan being eight months pregnant with his child, another insider says it’s ultimately the pregnancy that drove the exes apart.

“He didn’t want a child yet. He was scared. But Jordan wanted to keep it,” the insider tells In Touch. “Tristan was mad about the baby and left Jordan for Khloé. He and Jordan were still living together when Khloé opened her arms to him.”
