Kim K's son weighs as much as a pineapple

The 'Keeping Up With The Kardashians' star - who is expecting her second child, a son, with husband Kanye West next month - has revealed her baby currently weighs 7 pounds, nearly double that her two-year-old daughter did in her third trimester.

She wrote on her official website: "He's [the weight of] a REALLY heavy pineapple, LOL! [I have] Anxiety, knowing my baby is so big and I'm gaining a lot of weight. My doctor wants me to manage it better, but it's hard to!

"I have gained more than I did the first pregnancy. I'm up 52 pounds so far, with six weeks to go. North was just four pounds, so this is new to me. This baby is already seven pounds."

Meanwhile, the 35-year-old television personality and the 'Bound 2' rapper are said to still be unsure on what name to call their little tot.

A source said: "Kim wasn't crazy about [an unusual moniker]. Kim won't solidify the name until the month she gives birth."

It is thought Kim is "likely to have a C section" and is planning on reserving a luxurious three-room suite at Cedars-Sinai Medical Centre in Los Angeles.
