The new romance comes after Scott was linked to a string of young beauties, most notably Bella Thorne, 19, during the past several months.

He has been separated from former partner Kourtney since 2015 and the two share three kids: Mason, seven, Penelope, five, and Mason, two. 

His latest antics aren’t the only ones making headlines in the Keeping Up With The Kardashians world.

It’s been claimed that the 20-year-old is four months along with a baby fathered by rapper Travis Scott whom she started dating in April after splitting from longtime boyfriend Tyga, whose ex Blac Chyna is mother to Kylie’s half-brother Rob Kardashian’s ten-month-old daughter Dream.

Kylie and other members of her family have yet to confirm the pregnancy.
