An insider tells OK! that Scott Disick, 34, has hatched a new plan to get under his ex’s skin: having a baby with his 19-year-old girlfriend, Sofia Richie!

“Scott is upset that the Kardashian’s have cut him out of their circle,” shares the insider.

“He’s not actively trying to get Sofia pregnant, but he’s not being careful. With all the fuss over Kylie and Khloé’s pregnancies, he knows having a baby would blow up their world.”

Though the insider claims that Scott is playing up the seriousness of his relationship for attention, Sofia is on board with his twisted idea.

“Scott knows that this relationship could end just as quickly as it started, but he’s desperate to prove that he’s moved on from Kourtney,” says the insider.

Needless to say, the young model’s loved ones think she’s making a —­ though their pleas to slow things down are falling on deaf ears.

“Sofia’s friends know Scott is a womanizer who’ll only break her heart,” says the insider. “They’re begging her to reconsider being with him, but she won’t listen.”
