Kourtney Kardashian may be pregnant with her fourth child, a new report said Tuesday. TMZ’s sister website Fishwrapper hinted at the possibility citing Kardashian's recent pictures in which she was spotted wearing a one-piece swimsuit instead of a bikini.

The website also speculated the father of the baby could either be Scott Disick or “the one other person she’s really been linked to after splitting with Disick ... [Justin] Bieber?”

However, Gossip Cop debunked the report, citing Kardashian's representative who said she is not pregnant.

The "Keeping Up With the Kardashians" star split with Disick last July after nine years together, following which the two have been linked to several people.

Most recently, the 37-year-old was rumored to be dating Canadian singer Justin Bieber. Reports also said that despite romancing Kardashian, Bieber was hooking up with his ex-girlfriend Selena Gomez again.

A recent report said that Kardashian wanted to hold on to Bieber despite being insecure over his romance rumors with Gomez. Bieber and Kardashian reportedly ended their brief romance after rumors about their dating surfaced. However, the two were later rumored to have gotten back together.

Bieber began dating Kardashian because he considers older women to be “dominant,” while the reality TV star was involved with him in a bid to annoy Disick, People magazine said.
