Kylie Jenner can't keep her hands off rap star boyfriend Tyga during an upcoming episode of "Keeping Up with the Kardashians."

E! Online reports after the hip hop star joins the family on their vacation to St. Barts, his teenager girlfriend is overcome by emotion when she spots him arriving on the island.

"I am so excited to see Tyga," she raves. "I love having T around, I feel like he just keeps me sane and he always wants to do everything that I want to do and we love going on adventures."

However, not every family member was quite so happy to see the "Rack City" rapper arriving.

"You could have taken this time to be with your family," older sister Kendall rages after Kylie rushes into her man's arms and gleefully sits on his lap.

The trip was meant to be a bonding experience for the family and with Tyga now part of the mix Kendall seems convinced her sister's focus will completely be on spending time with him.

If the young couple has any chance of surviving over the long haul, that might not be such a bad idea, given all the drama they've recently experienced.

Kylie was a recent no-show at her boyfriend's 26th birthday celebration amid rumors the two were feuding and may have even split. In addition, both have recently been dogged by allegations of being unfaithful to the other.

In the case of Tyga, transgender woman Mia Isabella recently claimed they had an ongoing relationship and, around the same time Kylie celebrated her 18th birthday, Miami rapper Stiches claimed they had sex and did drugs together.

He added Kylie later started blocking his calls, leading him to compose the diss song "Kyga She's a Liar."
