Kylie Jenner and Tyga Flaunt PDA on Ski Vacation in Mammoth Lakes

The only thing cooling off between Kylie Jenner and Tyga is the temperature. The 18-year-old Keeping Up With The Kardashians star and the 26-year-old rapper were spotted in Mammoth Lakes, California, a popular ski vacation destination, on Saturday following the New Year's holiday.

Jenner and Tyga are heating things up even on a ski trip, proving to everyone that they are still very much together and are still totally in love while they show off some romantic PDA.

An eyewitness told E! News that the duo were spotted grabbing some snacks at Von's supermarket with a group of friends. At one point, the youngest Jenner was even seen leaning against the rapper's chest as they were waiting in line to check out, according to another source.

An onlooker snapped a photo of the couple and posted it to Twitter with the caption: "Saw Kylie Jenner and Tyga at von's in mammoth."

Their holiday appearances had mark the first time that they have been seen together in almost a month following a short breakup.

Jenner reportedly dumped her much older boyfriend in November. A source told HollywoodLife exclusively that “Kylie ended it with Tyga when she got back from Australia,” noting that Caitlyn Jenner's youngest daughter was suspicious that the rapper was cheating on her while she was away.

The reality star discovered “something on his computer that made it clear that he had done something wrong,” the insider added.

Since then, Tyga had been proving his innocence and his love for Jenner, and judging by their recent holiday trip, it looks like they're definitely back on track.
