Earlier this week, it was revealed that the couple had parted ways for good.
Kylie is yet to discuss the end of the relationship, but rapper Tyga spoke to TMZ while at Los Angeles airport. He explained: "We're both focused on our individual lives right now and sometimes things don't work out, but I love her."
Although neither have explained the reason behind their break-up, many reports have suggested that it was trust issues which led to the couple going their separate ways and that Kylie,18, "couldn't trust a word he said".
A source told People Magazine that Kylie was feeling "insecure about their relationship" and that she had caught Tyga, 26, "lying and talking to other girls behind her back before".
It went on to add: "He was lying repeatedly to her face and she just couldn't take it anymore. She was over it."
Kylie and Tyga confirmed their relationship when Kylie turned 18. Last November, there were rumours suggesting the pair had broken up, but Kylie later denied the whisperings.
However, this year, their relationship may have taken a possible strain when Kylie's brother, Rob Kardashian, revealed he was dating Blac Chyna, who just so happens to be Tyga's ex-fiancee - they even have a son together, King Cairo, three.
And just last week Rob and Blac announced they are due to become parents, as Blac is pregnant with their first baby.
Showing no signs of moping around after the split, Kylie was snapped partying with Scott Disick earlier this week.
