Plus, RiRi reveals she was sick at her gig in Lisbon on Saturday...
Rihanna has vented her anger on Twitter after becoming the victim of racial abuse in Portugal.
The Bajan babe, who was in Lisbon while on tour, came face-to-face with "the most racist man ever" at her hotel in the city, claiming he attacked her with a series of discriminative slurs.
Speaking on the social-networking site last night (18th December), RiRi tweeted:"I just met the most racist c*** EVER!!! This man said the craziest shit abt black women called us dogs, sl*ts, we don't look like s**t, we don't belong in the same hotels."
The 23-year old continued: "Needless to say, the #NIGGA in me came out! Bajan accent and all! Lol! Turns out the hotel manager's black. Oh and he had the NERVE to diss black people in his Tighty whitey's!!!! SMH...and tbh a lil black wouldn't hurt him."
The We Found Love singer had previously revealed on Twitter that during her concert at Lisbon's Atlantico Arena on Saturday (17th December) she was forced to leave the stage to be sick, after a feeling a little under the weather.
Rihanna confessed: "Portugal tonight was legendary!!! I ran off stage to throw up, halfway thru What's My Name... made it back juuuust (sic) in time for Rude Boy."
Despite her bout of sickness, the sexy singer appeared to be feeling better last night, telling her followers: "We just had our end of year/tour Christmas party!!!! We turned it into an 80's prom, since I've never had one! It was sooo (sic) much fun!!!! I'm decked out in lace, sequins, a giant bow, and hair spray!!!!!"
