Kourtney Kardashian: Essentially a Single Mother!

Stop us if you've heard this before: Scott Disick is an irresponsible jerk who is leaving Kourtney Kardashian at home to raise the couple's children.

So screams yet another recycled tabloid headline, as this week's Life & Style quotes an anonymous source who claims Disick "doesn't share" Kourtney's "love for being a parent."

Staying out until the dawn, taking shots, cracking sexual jokes, "Scott's totally out of control," the magazine mole says. "He's doing whatever he wants to do."

Kardashian and Disick welcomed Penelope Scotland Disick into the world on July 9 and even with her and little Mason Dash at home, the source says Scott continues to live a bachelor lifestyle.

"He's definitely back to his old ways," reports the tabloid, adding that "Kourtney's looking into getting a nanny" and even considering a job at a Los Angeles Dash branch so she can support herself financially.

Right. Because the six figures she makes from E! and the seven figures she'll sell the baby photos for clearly aren't enough.
