Tweet fight: Joan Rivers vs Rihanna

Rihanna is still talking about Chris Brown; breaks down during Oprah interview

Rihanna told Oprah:

'I felt like the only person they hate right now is him. It was a weird, confusing space to be in.Because as angry as I was - as angry and hurt and betrayed - I just felt like he made that mistake because he needed help. And who's going to help him? Nobody's going to say he needs help, everybody's going to say he's a monster, without looking at the source. And I was more concerned about him. It was embarrassing it was humiliating... I lost my best friend.'

She also said:

'I am super duper terrified of the pedestal that comes with fame..It's amazing how lonely you can feel.'

Rihanna Takes Off Her Clothes In New Commercial For Armani Jeans

Rihanna looks lovely wearing Armani on the cover of Vogue UK's November issue, but then turns up the heat as she strips out of a dress by the Italian designer in a new Armani Jeans commercial. Apparently the recent lecture on modesty she received from an Irish farmer went in one ear and out the other.

In this sizzling teaser for the commercial, Rihanna is seen unzipping her dress and pulling it down over her hips to reveal lacy underwear as she sings, "I got a secret I wanna show you."

Ooo la la! We'll have to wait until the full video drops to see what the secret is, but I'm sure you can guess.
