That's one way to stop traffic!

While crossing the street after dining with beau Scott Disick, Kourtney Kardashian flaunted her cleavage in a Bebe maxi dress. But the 31-year-old says she didn't intend to put her boobs on parade.

"My boobs may be a little big for my dress since I'm breast feeding," the Kourtney and Khloe Take Miami star blogged Wednesday. "[But] the weather in L.A. is perfection right now...I can wear pretty much anything and be warm!"

After leaving Yu + Mi Sushi in Beverly Hills, Kardashian -- who gave birth to son Mason in December -- said she felt self-conscious and hates "when you run out of the house in a rush and then don't feel comfortable."

But the new mom -- dressed in YSL shoes and armed with a Balenciaga bag -- adds that it's only a matter of time until she's comfortable flaunting her curves again.

"I do love the dress," she says. "Just a little too much 'cleave' for my newmama self!"
