Kourtney Kardashian is reportedly pregnant with baby No.3.

The reality TV star is expecting her third child with husband, Scott Disick, according to Us Weekly, which claims "multiple sources" revealed the information.

"She is only a few months along," an insider told the mag of the oldest Kardashian sister.

Kourtney is already showing a pregnancy glow, according to a guest at the Trump SoHo hotel, where she stayed after returning home from attending Kim and Kanye's wedding in late May.

"Kourtney looked really pretty. She had a nice flush on her cheeks," said the guest.

The 35 year-old 'Keeping Up With The Kardashians' star, and Disick, 31, are already parents to a son, Mason, 4, and a daughter, Penelope, who is 2 next month.

"It was planned," another source told the gossip magazine. "[Kourtney] wants to have a handful of kids."

Fans of the reality show would already know Kourtney's view on birth control, back in 2012 she stated on an episode that she is going to stop it forever.

"I need to see what it's like when I have two, but [having kids] is what life is about," she said at the time. "I'm not going on the pill. I don't believe in it anymore!"

The happy couple will allegedly welcome their newborn into the word this coming December. "They don't know the gender yet," a third source said. "They just want the baby to be healthy."
