Keeping Up With The Kardashians: Kourtney flashes some serious sideboob in a skimpy swimsuit as she and bikini-clad Kendall cover themselves in MUD.....

They feared their relationship wasn't as close as their other siblings.

And Kourtney Kardashian and her little sister Kendall Jenner certainly stripped things back to basics as they went on a bonding retreat.

The mum-of-three, 38, and the supermodel, 21, headed to Santa Barbara to go wine tasting - and it wasn't long until they were showing off their famous bodies.

Relaxing in a hotel suite, the pair showed off their amazing figures in swimwear, with Kourtney looking amazing in a high-cut black one-piece with Kendall in a racy bikini.

The pair indulged in a beauty routine, covering themselves in mud as they slathered on a green face mask.
Kourtney was having the time of her life as she flashed some serious sideboob while rubbing the mask all over her behind.

Earlier in the day, the pair had got drunk while knocking back an array of wines.
