Rihanna Tickets

'Russian Roulette' singer Rihanna has insisted that she will be the only person allowed to tweet posts via her official Twitter account.

The 22-year-old, who is currently dating Matt Kemp, will no longer allow tweets from her label Def Jam/SRP.

The singer tweeted: "So now that I took over my Twitter page, no more corny label tweets.....lol! Whaaasssuup ppl! (sic)"

Interesting that shortly after Rihanna's announcement, her ex-boyfriend Chris Brown tweeted: "TWITTER JUST GOT WACK!!!!!!."

Think he was making a certain reference or is it just coincidence?
