What is more unexpected of a sight to see than a thin Rob Kardashian?
How about a happy Rob Kardashian?
The embattled reality star flashed his pearly whites in a number of Snapchat videos shared on that social media service over the weekend by girlfriend Blac Chyna.
And why shouldn't Kardashian have been all smiles?
The 28-year old was taking off for Jamaica alongside his very serious lover.
According to E! News, all talk of a Kardashian-Blac Chyna break-up has clearly been premature, as the two boarded a flight at Los Angeles International Airport Saturday night for Montego Bay, Jamaica.
They landed in this sunny destination on Sunday morning.
"Jamaica? Jamaica..." Chyna says to her boyfriend at one point in one of her videos, with Rob also capturing several moments between him and his girlfriend on Snapchat.
Kardashian later shared a clip of the gorgeous beach view from their hotel.
Blac Chyna, of course, is the mother of Tyga's infant son.
And Tyga is dating Kylie Jenner.
So Rob's family has taken extreme issue with this relationship over the past few months.
However, Rob was hospitalized and diagnosed with diabetes in December after struggling with weight issues since early 2014.
Ever since he started to get it on with Blac Chyna, though, Rob has shed a significant amount of weight; the 27-year old model appears to have helped him lose these pounds.
She has also helped get him out of his social media shell, while clearly putting the occasional smile on Rob's face.
Perhaps it's time for Kim, Khloe and kompany to accept that their brother is happy... and that Blac Chyna is the reason why.
