Rihanna, Cher, Katy Perry, More Stars Tweet About VMAs

Diddy promises to set the 'stage on fire' as a performer next year.

Although the curtains have closed on the 2010 MTV Video Music Awards, the show goes on in the form of Twitter reactions from the various celebrities in attendance Sunday night. From the show's various performers to mere spectators out in the crowd, just about everybody has had something to say about this year's event.

The first big surprise of the show occurred when Rihanna unexpectedly arrived to sing "Love the Way You Lie" opposite Eminem. The R&B artist wasn't expected to appear at the VMAs, but Rihanna stormed the stage nonetheless, later explaining to her fans on Twitter: "SURPRISE!!! Just had to do it guys."

Rihanna's performance alongside Slim Shady was considered one of the highlights of the night, especially for Paramore vocalist Hayley Williams. "The best thing was seeing Eminem live," she wrote, "and being only a few feet away from Gaga."

Indeed, it was hard not to notice Lady G, what with her eight VMA victories and her now-infamous meat dress. Legendary singer and actress Cher got an up-close glimpse at Gaga's controversial wardrobe, describing it as "interesting" and "amazing."

"The way it was cut and fitted to her body was amazing! The meat purse was genius," she assessed. "As [an] art piece, it was astonishing!"

The show moved along at a brisk pace, thanks to the hilarious work of host Chelsea Handler, though there was at least one attendee pining for last year's host, Russell Brand. "California Gurls" singer Katy Perry, who began her relationship with Brand at the VMAs in 2009, offered a tribute to her fiancé and told him that he was with her "in spirit." Brand responded with a promise to see Perry in Los Angeles later in the week.

At the end of the day, it was Kanye West who stole the spotlight for his second year in a row. Rebounding from his controversial stage-crashing at last year's awards, Kanye brought the house down at the end of the evening with his new song "Runaway." The new tune attracted praise from many of the show's attendees — including "Jersey Shore" star Vinny Guadagnino — and Kanye himself addressed his Twitter followers just hours before his performance.

"I wish my Mom was here but I know she's looking down," he wrote. "I want to make her so happy today."

Kanye closed out the 2010 VMAs in style, but we can already look ahead toward next year's show thanks to the promise from Diddy : "Next year imma set that f---in' stage on fire! See y'all then!"
