On Wednesday, Drake was a surprise guest on the Miami stop of Rihanna’s World Tour and the two put on a raunchy display while performing their hit song, ‘Work’, to the delight of their fans. But it looks like their antics pissed off Rihanna’s ex-fling, Travis Scott, who went on twitter the same night Rihanna twerked up a storm on Drake, to tweet S.M.H, after being away from the social networking site for over a week. He then canceled an appearance at SXSW the following day! Aww! See more pics of Rihanna and Drake having a ball and Travis’ tweet after the cut..
