Rihanna continues to hit rough patches in her Loud Tour. In her Lisbon, Portugal stop, she threw up on stage in the middle of a song and had a nasty encounter at her hotel with a racially abusive jerk.

The Bajan singer has missed several shows because of “exhaustion” and has complained about being light-headed.

Her latest incident, on the stage at the Lisbon’s Pavilhão Atlântico over the weekend, even sparked rumors that she may be pregnant.

“Portugal tonight was legendary!!!” she Tweeted with what must have been a note of sarcasm.

“I ran off stage to throw up, halfway thru What’s My Name… made it back juuuust in time for Rude Boy,” she Tweeted referring to her set list.

She has been on a grueling tour schedule since June, amid reports that she was working overtime to finish her album as well has hitting the clubs almost every night and downing tequila shots.

She tweeted a shocking photo of herself at the time, hooked up to an IV drip in a hospital in Sweden, while tweeting her apologies for canceling a show.

If that’s not bad enough, she went ballistic on Twitter over a chance encounter with “the most racist” man she’d ever met.

“I just met the most racist c**t EVER!!!” she Tweeted.

“This man said the craziest s**t about black women – called us dogs, sl**s, we don’t look like s**t, we don’t belong in the same hotels.

“Needless to say, the #N**** 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 (shake my head)…and tbh (to be honest) a lil’ black wouldn’t hurt him.”

Fortunately, the tour wraps up Dec, 22 at the O2 Arena in London. Then, hopefully, Rihanna will kickback for some rest.
