Kourtney Kardashian's kids were too sick to go to Thailand.

The 'Keeping Up with the Kardashians' star, 34, and her partner Scott Disick, 30, were forced to pull out of her family's recent trip to Phuket because their children, Mason, four, and Penelope, 19 months, ''came down with a cold.''

A source told E! News that the children ''were too sick to fly'' from Los Angeles to South East Asia with Kourtney's mother Kris Jenner, sisters Kim and Khloe, half-sisters Kendall and Kyle Jenner, step-dad Bruce Jenner, and his sons Brody and Brandon, who was joined by his wife Leah.

But the couple enjoyed a ''mini-getaway'' to nearby Santa Barbara while the rest of the family soaked up the sun in Thailand.

The source also dismissed speculation that Kris and Bruce, who announced they were separating after 22 years of marriage in October, are back together after they were spotted holding hands at LAX airport on Wednesday (02.04.14), and insisted they are just ''friends.''

Bruce, 64, decided to move into his house in Malibu following the split while Kris, 58, stayed in their family home in Calabasas.
