Party Of Three! Kourtney Kardashian Dons Leather Ensemble While Out To Dinner With Son Reign & Boyfriend Travis Barker — Pics

So much for alone time! On March 25, Kourtney Kardashian and new boyfriend Travis Barker were joined by her 6-year-old son, Reign Disick, when they went out to dinner at Malibu hotspot Nobu.

Though his hood covered up the tot's head, Disick was rocking his new shaved hairstyle, which could have been inspired by Barker himself!

Scroll down to see photos from the trio's outing.

While the reality star donned a brown leather trench coat, matching pants and a white tee, Barker stuck to basic black. Both of the stars' face masks coordinated with their ensembles.

According to an insider, the Blink 182 alum "is spending so much time at Kourt's place that he's in to make it easier for them to visit him there."

"It's an easy transition since he also lives in the neighborhood," the insider added. "Everyone's convinced they'll be living together full-time before you know it!" 

The couple publicized their romance on social media in February, with the Poosh founder posting a photo of them holding hands. A few days beforehand, the pair celebrated Valentine's Day together.

It was reported in January that the duo had already been dating "for a month or two. Travis is very smitten with Kourtney and has been for a while," an insider revealed.

Kardashian and ex Scott Disick's youngest child — they also share son Mason, 10, and daughter Penelope, 8 — looked comfy in a maroon velour sweatsuit, which he topped off with a varsity jacket that featured white sleeves.

"Travis has been a friend of the family for years, so the kids have pretty much known him their whole lives," an insider told OK! of the musician's relationship with Kardashian's three kids. "They'll do fun stuff together, like hiking or playing video games, and Travis loves making breakfast and showing off his pancake-flipping skills." 

Another photo showed the mother and son duo holding hands. Disick also seemed to be sporting white Yeezy sneakers — hopefully aunt Kim Kardashian gave him a discount!

Barker has son Landon, 17, and daughter Alabama, 15, whom he shares with ex-wife Shanna Moakler.
