Though Kim Kardashian just flew with baby North to Australia last week to join Kanye West on his "Yeezus" tour, the couple is reportedly having marital issues. While they look happy, and Kardashian has been posting numerous photos of the two on Instagram, the reality star and her rapper husband have been slammed with divorce rumors lately.

“Kanye and Kim cannot stop fighting,” a source tells RadarOnline. “He doesn’t trust her at all, and she is suffocating! Kanye nags her about everything and he even chooses who Kim can and can’t hang out with. Her friends cannot even be around her anymore because she is not allowed to have any girl time. … She puts on a brave face, but anyone who knows her can see right through it.”

This is not the first time it has been speculated the two may split. Earlier this summer, Kardashian was said to be second-guessing her decision to marry West, because his controlling behavior was reportedly too much for her. They married in May in front of close family and friends in Italy.

If the marriage does end soon, it won’t be Kardashian’s first brief marriage. In 2011, she got engaged to NBA player Kris Humphries after dating for seven months. The couple was married for only 72 days before filing for divorce.
