Who’d have guessed these two shared clothes?

What’s impressive is that Rihanna rocked the sweater dress at dinner in LA on Wednesday night — and then sent it on a transAtlantic flight to London, so Katy could slip it on for a night out in the British capital!

… Unless it’s not one-of-a-kind

We prefer our theory.

Rihanna is going to extremes to make sure her 2010 tour is a hit ticket – literally!

She has hired guitarist Nuno Bettencourt from 90’s band Extreme to join her on the road.

It might seem like an odd link up – but Nuno’s a big fan of Rihanna’s music: “This is my thing, this is my style.”

Get the Funk Out!!!

What happened to Rihanna?

We spotted the singer returning to her London hotel last night sporting a suspicious bump above her eye!

Want to know how Rihanna stays in shape?

So do we, because we don’t buy her recent claim she feasts on junk food on tour!

“I eat pretty much whatever I can get my hands on. There’s always noodles, a lot of microwave meals, endless chips and snacks and bad stuff.”

That doesn’t seem fair!

He’s not allowed within 100 yards of Rihanna, but Chris Brown isn’t letting a court order stop him from using his ex to boost his career.

No sooner has Rihanna signed up for an appearance on news show 20/20 on Friday night, but Chris arranges his own interview, four hours earlier, on MTV.

And we find out today he’s now bumping the release of his next album, so it comes out just two weeks after Rihanna’s Rated R.

Still… there’s some good news for the Brown haters — despite his claims ticket sales for his new tour are “going well” there’s still a ton on offer, and it starts next week!
