Breaking:Kourtney Kardashian leaves famous family behind as she jet sets to NYC with baby son Rocky

The Kardashian mom-of-four cheered on her husband Travis Barker this weekend.

Kourtney Kardashian-Barker traded her sprawling $9 million Calabasas mansion for New York City this weekend, jet-setting to the east coast to cheer on her husband, Travis Barker, as he hosted his run club in the city.

Kourtney, 45, caught up with a friend for a baby playdate shortly after touching down in NYC, resharing a sweet photo of her eight-month-old son Rocky playing with a friend to her Instagram Story.

The eldest of the Kardashian sisters appeared to travel without her famous sisters, nor did she share any photos of her Mason, 14, Penelope, 12, and Reign, nine during the trip, whom she co-parents with her ex-partner Scott Disick.

Kourtney and Travis welcomed baby Rocky Thirteen in November, and the doting mom hasn’t been apart from her little one since.

Explaining the reason for her closeness with her baby, Kourtney said in a confessional on The Kardashians: “I’m really into attachment parenting. I really don’t separate from him,” adding: “I feel like my time is dedicated to taking care of my baby and bonding with him.

“She took on a similar philosophy with Penelope and Reign, as she told Vogue: “That’s what I did for my last two kids, we didn’t leave the house for the first 40 days. After, you’re super-connected and I love that.”
