Just last month, Barker showed his love for Kardashian by inking her first name on his chest directly above his left nipple.

The romance has continued to heat up between Kardashian and Barker, who went public with their relationship by going Instagram official over Valentine's Day weekend. From sharing a cheeky Goop candle named "This Smells Like Kourtney's Orgasm" to packing on the PDA during a romantic getaway in Utah, the couple hasn't shied away from showing off their romance on social media.

"He's liked her for a long time and she just got more open to the idea. He's a good guy and a really great dad," the insider said in January. "Her family and friends all really like him. Their kids all get along too, which is sweet."
