They've been reportedly working on their marriage, but Kim Kardashian has jetted off on a trip with her family, leaving her husband Kanye West behind.

Kardashian, along with her children, North, 3, and Saint, 1, her sister Kourtney and her kids, Mason, 7m Penelope, 4, and Reign, 2, Kris Jenner, Corey Gamble , Khloe Kardashian, Kylie Jenner, Tyga and his son, King, jetted off for a vacation to Costa Rica on Thursday, according to People Magazine.  

"They are all excited about the trip," a source told the magazine. "it will be relaxing for them, but also adventurous with activities like rain forest zip-lining planned. They will be filming for the show the whole time."

However, notably missing are then men involved in all the Kardashian women's lives, including Khloe's boyfriend, Tristan Thompson, Kourtney's on/off boyfriend and the father of her kids, Scott Disick, and West, but the source maintains that at least in the case of West, he had other commitments which kept him from the trip.

"[He] was never supposed to come. He is busy working on his music in LA," the source said.

The couple's relationship has been the subject of endless rumors of an impending divorce, after they suffered through a tough few months at the end of 2016. Kardashian was robbed and held at gunpoint in Paris in October, and West was hospitalized for exhaustion in November.

As for Disick, he was not allowed to come on the trip after he partied at the Sundance Film Festival, where he reportedly flirted with a woman who looked similar to Kendall Jenner.

"Scott is still in the dog house from partying at Sundance," the source said. "Kourtney disinvited him."
