EXCLUSIVE PHOTOS – Pregnant Kourtney Kardashian Is Almost Ready To Pop!

Kourtney Kardashian went to a doctor's appointment in Beverly Hills today, and the preggers reality starlet was in good spirits when we snapped her coming and going.

Kourtney is due sometime in June, and while she previously revealed that she's having a girl, she hasn't given us any hints as to what she might be naming her daughter. "I love being pregnant!" she tweeted. "Such a magical and beautiful feeling. Feeling blessed!"

However, yesterday she wrote, "Having a lot of siblings is essential. When you are hating one, there are more to love. I might need to have a whole bunch for my children!" We're not sure where that came from, but rumor has it Kourtney suffered a "meltdown" after seeing her sister Kim flirting with baby daddy Scott Disick!

According to OK! Magazine, Kim and Scott were chatting “a little too closely and a little too long” at the New York City opening of his new restaurant RYU last month. Kourtney apparently felt "betrayed" by Kim's actions, and a source tells the mag, "Anything can set her off and send her into the most vicious temper tantrum." Yikes!
