Kourtney Kardashian's Boyfriend Travis Barker Jumps In As Stepdad To Scott Disick's Youngest Son During Day At Disneyland

The Keeping Up With The Kardashians star and her Blink-182 rocker beau proved to be doting parents at the Happiest Place on Earth with Kourtney's youngest son.

The 42-year-old mom and 45-year-old drummer looked like teenagers during their day at the theme park on Wednesday.

Despite having five kids between them, Kourtney and Travis only brought Reign for some one-on-one time with the couple.

The Poosh founder soaked up the sunshine, flaunting her famous curves in an itty bitty backless top with baggy black pants.

Travis went full rockstar, wearing a sheer long-sleeved shirt to showcase his body full of tattoos.

Sporting a beanie in the middle of summer, Travis couldn't stop touching Kourtney at the theme park.

The duo held hands the whole time during their day at Disneyland.

Travis was even seen planting a sweet kiss on Kourtney's cheek as the two sat with Reign to ride Dumbo.

The Blink-182 drummer wasn't just adorable with his girlfriend, but he also showered her son with affection.

Travis showed off his childlike side when he rode Big Thunder Mountain Railroad with Reign not just once but twice.

The duo seemed to get along just fine, and the rocker was photographed carrying Kourtney's son on his shoulders.

Travis is slipping into stepdad without any trouble at all and even held Reign's hand throughout the park.

Despite declaring his love for Kourtney last season on KUWTK, Scott Disick gave her relationship with the musician his kiss of approval.

When asked about her PDA-filled romance with Travis by Andy Cohen during the show's reunion special, Disick gave the couple his blessing.

 “I think if you really love somebody, right, you want them to be happy no matter what. So I do give her a blessing to be happy," he said on TV.

Despite giving his approval, something tells us Scott didn't give Kourtney the okay for a PDA-filled day in front of their kid.
