Mason "Birth Control" Kardashian
by Ryan Porter
Kim says her seven-month-old nephew is her most effective form of birth control.

That
Kim Kardashian. Such a trail-blazer! In addition to her tireless efforts to teach people to get bikini-ready, she's pioneered a new form of birth control. It's called spending time with a seven-month-old baby.
"Let's just say
Mason is the best birth control ever," the 29-year-old said, referring to her sister
Kourtney's baby on Ryan Seacrest's radio show on Thursday (via
People). "I'm happy to wait a few years."
Another fabulous Kardashian birth control secret: not dating. Although she's been linked to yet another in her popular Footballers of the World series, Dallas Cowboys wide receiver
Miles Austin, since breaking up with her long-term boyfriend
Reggie Bush in March, her official status is single.
She told Ryan she's "having a good time, meeting some really great people and trying to live my life," adding "I'm definitely in a huge love affair with my career right now!" But does your career take you out for dinner, give you diamonds, and tell you you're beautiful? It does? Well then, who isn't in love with Kim Karadashian's career?
