Kim Kardashian to film birth and pregnancy with baby bump time lapse

North West's future baby brother had better get ready for his close up.

Because Kanye West and Kim Kardashian West are reportedly shelling out over US$150k for their own personal camera crew to, get this, film the progress of Kim's pregnancy.

"She's offered them a pretty penny to shoot with her on one day a week for the rest of her pregnancy," a source told The Mirror's 3am. "Kim and Kanye will fly the crew to wherever they are in the world for the shoot.

"And Kim wants them to film the birth for their own private video. It will never air publicly but Kim says she wants a reminder every day of the birth, as this baby may be their last."

Kim, 34, is apparently a huge fan of the time-lapse pregnancy craze, which takes images of a pregnant woman sitting or standing in the same spot and later compiles them into a film.

The reality TV star, who is four months pregnant with the pair's second child, is reportedly hoping to land the same team who captured her 2014 wedding to Kanye, 38.

"The camera crew are discreet and that is what Kim and Kanye like about them," the insider said.

We sure hope it's better quality video than their first dance clip shared on Kim's Instagram. Watch below…
