Kourtney Kardashian and Travis Barker are very much in love, according to a source.

The reality star said “yes” to Barker’s proposal without hesitations despite only dating for a few months.

A source revealed: “Her thoughts definitely changed when she and Travis became official. Those two spend all their time together and are madly in love.”

The source added: “They're almost like high school sweethearts all over again. Neither of them ever thought they'd fall in love like this again.”

Kardashian received a marriage proposal in the past from ex Scott Disick, but she turned him down despite being in a relationship for 10 years.

Barker has a great relationship with his kids and Kardashian’s children.

He taught Kardashian’s daughter Penelope how to play the drums.

An insider revealed: “He's so sweet and loving towards her and her children.”

The same source added, “Their families also blended easily and nicely, and they all get along so well.”
