Word is Rihanna is becoming quite a diva…especially when it involves her having to wait! The Bajan beauty has been in London promoting her new album, Rated R and apparently went straight into b*tch mode when her driver picked her up three minutes late. A snitch reveals,

“She was with a massive entourage and one was on the phone to the driver, asking where he was. Suddenly Rihanna started shouting in the face of this guy, saying: ‘Where the f*** is my car?’ After another minute, she squawked, ‘I mean it guys, you’ve now got 30 seconds to get me my car or someone is losing their employment. I f***ing mean it, 10 seconds and I get nasty’.”

According to the snitch, the driver arrived a few minutes later and was so shook that his ass almost drove the wrong way down the street.

In related news, in a recent interview with ATL’s The Bert Show on Q100 Rihanna admitted that despite her beatdown drama with ex-boo Chris Brown, she does miss him at times and still listens to his music.

When asked if she misses Chris Brown:

“Um…sometimes. Actually yes! Uh..there are a lot of reminders. Like a lot of hotel rooms, like places that we’ve been to together. Um…music, there are different things that come up that are just reminders of your ex. I’m sure you know what that feels like.”

When asked if she listens to Chris’ music:

“When it comes on on the radio, I don’t snob or turn it off. I just listen. You know? I like his music. She adds, “I’ve gotten over it. Um…but there’s definitely constant reminders. And a lot of it listening to the radio and the songs coming on. Songs that were our favorite songs are his songs.”

Yesterday, we reported that Rihanna and 90210 actor Tristan Wilds are supposedly seeing each other after being spotted getting cozy at her house party this past weekend. According to Rihanna, it’s just a rumor and nothing more. She laughed off the false story–claiming she doesn’t even have his number.

Word is Rihanna is really feeling 90210 actor Tristan Wilds. According to the NY DailyNews, this became evident this past weekend during a party at the singer’s L.A. home in which Tristan was a guest.

“No one knew why Tristan was there initially, because it was not an industry party — it was very intimate,” says a fellow guest. “But everyone quickly realized they weren’t meeting for the first time, because they were openly affectionate for everyone to see.”

And the snitch claims sparks flew from the moment they met.

“He’s a real gentleman,” says the snitch. “She likes him a lot, and it shows. From the moment he walked into her party, Rihanna lit up.”

Although Rihanna is in major promo mode prepping for the release of her album, the snitch reveals that the “couple” have come up with a plan to make their fling last.

“They’ll keep in touch while she’s away.They’re already planning to use iChat and Skype to stay in contact until Tristan finishes shooting ’90210′ for the season and can fly out to meet her on the road.”

In related news, the Bajan beauty will perform her new single Russian Roulette from her new album Rated R on Britain’s “The X Factor” on Sunday, November 29^th. However, she’s not the only star on the bill for that night. Alicia Keys will also be performing “Doesn’t Mean Anything” from her new album, The Element of Freedom.
