Kourtney Kardashian Ready for Baby No. 3?

Kourtney Kardashian and Scott Disick are said to be preparing for a third child just four months after the birth of their newest addition, baby Penelope Scotland Disick.

The reality TV stars, who also share a 2-year-old son Mason Dash, are reportedly eager to have another child by mid-2013. Another source claims that Kardashian, 32, may be expecting by the end of 2012, according to a report.

"[Kourtney's] not only talking about getting pregnant again by summer, she's making some plans," a family insider reportedly told OK! magazine.

"It's at the point where Kourtney is almost addicted to being pregnant. It really does change her outlook on life. Her mood, her attitude, and her temperament really change and she loves that feeling so much that she wants to keep the pregnancy high going," the source explained.

The pregnancy report follows speculation that the couple of six years is planning a televised engagement followed by a wedding, which some critics suspect could mimic her sister Kim's 2011 over-the-top nuptials to Kris Humphries.

Disick, 28, was reportedly spotted shopping for an engagement ring in Miami on Oct. 25 and critics believe that the couple may be planning to have another child and to wed for all of the wrong reasons.

"[Scott and Kourtney] are planning to get engaged when they tape the end of the season of Kourtney & Kim Take Miami in December," a friend close to the family reportedly told InTouch magazine.

"It's definitely just for TV ratings. Kourtney is getting caught up in the show, and he, of course, just wants the payday. Sadly, she's flirting with disaster- and everyone knows it," another source claims.

Kardashian is said to be determined to have a third pregnancy and the mother of two has reportedly booked an extended vacation during the spring time in preparation for a summer pregnancy. Disick is said to be equally as keen.

"[She's] going to take Scott away on an extended vacation to Turks and Caicos in early spring...[he] loves when she's mellow and pregnant," the insider said.

"I wonder if she'll actually wait for their spring holiday. Kourtney might be pregnant before the end of the year," the source said.
