Rihanna was in London this past weekend for the debut of her first-ever clothing line, a joint venture with the British brand River Island.  The looks on display at the launch event, which began nearly an hour behind schedule Saturday night because Rihanna was late, received some negative reviews -- The Daily Beast called the line "unsurprisingly slutty and yet tiresomely predictable."  But that wasn't even the most controversial part of Rihanna's London trip.

After the show, RiRi was involved in a confrontation at a London nightspot, and on Sunday morning her face was all over the British newspapers after one paper compared her to the late Princess Diana in ways that were not entirely flattering.

First the confrontation. While Rihanna was celebrating after the fashion launch at the London nightclub The Box, another patron threw a bottle of Lucozade, a British energy drink, in her direction.  The New York Daily News reports that the perpetrator also yelled at the singer about her on-and-off love affair with Chris Brown. Though the bottle missed, the singer managed to nick her knee which bled as she exited the club.

Then the next morning, Britain's Sunday Times magazine featured a cover picture of Rihanna's face melded with that of the Princess Diana, along with the headline "Why Rihanna Is the New Diana."

Rihanna had quite a reaction to the cover.

"Just so happens I came home drunk to this in a pile of papers outside my hotel room!" Rihanna tweeted, posting several shots of the British papers with the story about the comparison on the front page.  "My lil Bajan behind never thought these many people would even know my name, now it's next to Princess Diana's on the front of a newspaper! Life can be such a beautiful thing when you let it be #yourejealous :)"

She added, "When your face is pic-stitched to Princess Diana's on the cover of The Sunday Times.... I mean... #extraordinaRIHbehavior."

The comparison wasn't entirely complimentary though.  Written by feminist Camille Paglia, the piece compares the two women's ability to manipulate the world's media and says Rihanna "in the classic syndrome of the battered woman, still pities and hopes to change and save her abuser."
