Did Kourtney Kardashian give birth?

Is there another Kardashian amongst us? Oldest sister Kourtney set the Internet afire with word that she had given birth on Thursday night when she tweeted, "Chick-fil-A and a water birth. No big deal." But it was a big deal to the millions of fans who took the cryptic message as the reality star's hint that she was about to welcome her daughter into the world, even though she's not due until July.

But on Friday morning, Kourtney, already mom to Mason, 2, clarified in a follow-up tweet that she had only "witnessed" a water birth with her sister Khloe and that it was quite the experience. "All I can say is WOW," she wrote. So does this mean she's thinking about a water birth for herself? When she delivered Mason, which aired on "Keeping Up With the Kardashians" in December 2009, Kourtney shocked her family and fans alike when she painlessly pulled her son out and put him on her chest. A source tells TooFab.com that Kourtney, 33, was "merely doing research on water birth and got a little overexcited with her tweets."

Khloe must have been getting some pointers, too. The youngest of the Kardashian sister trio reportedly began fertility treatments this past Monday. Khloe has been vocal about the trouble she and hubby Lamar Odom have had conceiving. "She's finally doing this because she has the time now that she's in L.A. full-time again," an insider tells Us Weekly. Khloe had been going back and forth between Los Angeles and Dallas after the NBA star was traded from the Lakers to the Mavericks in December. But in April, he was let go from the team and returned to California. Her fertility issues have been "frustrating," Khloe said last fall during a "Today" show interview. "But definitely, I want to have kids."
