Whether they're steaming up Instagram or sharing glimpses of his new "Kourtney" tattoo, it's clear Travis Barker and Kourtney Kardashian dove right into their new romance—and aren't holding anything back.
While it's only been a few months since the Blink-182 rocker and POOSH founder started dating, these two longtime friends have not played coy about their feelings for each other with public displays of affection, family travel and Travis' candid declarations of love—not to mention the elaborate floral arrangement he gifted her in honor of her 42nd birthday.
"Travis adores Kourtney and makes every day special, especially her birthday. He has gone all out to shower her with love, affection, flowers and gifts," a source close to Kardashian said. "He is very into her and waited a long time to be able to show her how much he cares. He wants to spend all of his time with her and is constantly telling her how much he loves her."
While he may be the famed punk rock drummer, it's Kardashian who has "rocked his world and he is head over heels," the source noted. "She's really enjoying it and knows she is being spoiled."
While it sounds like Barker is very much smitten, it's not unrequited. "She's falling for him," the source said, "and not holding back."
As for why things are moving along so well, their past deserves some credit. "They have a long history, so it's been easy and comfortable," the source explained. "They are moving quickly because they know each other so well. Everything seems to click and they are both very happy."
A second source close to Kourtney tells E! News she's "head over heels" for her man, describing, "They truly have a bond like no other. No one has seen her feel this way about a man in a very long time."
Things have become so serious, in fact, that the insider says Kourtney has " expressed she would absolutely marry him."
"They have the best connection and communication, something that's very important to her," the source explains. "They are still in the honeymoon phase and it's going really well."
If that wasn't already clear, look no further than Barker's birthday tribute to the famous lady in his life. "I F--KING LOVE YOU!" he wrote on Instagram for Kardashian's special day. "YOU'RE A BLESSING TO THIS WORLD."
