The 'Umbrella' singer says the troubled star - who recently lost custody of her two children to ex-husband Kevin Federline following her erratic behaviour - is under too much pressure and thinks people should leave her alone.
She said: "I don't think there's anything wrong with partying, partying is healthy. You can't have a boring life. You have to party some time.
"People put so much energy into being negative about Britney. There's so much pressure on her - it can't be easy."
Although she is worried about the pressures of fame, Rihanna isn't concerned about having a high-profile relationship.
The sexy star is currently dating actor Josh Hartnett and admits she is smitten with him.
She said: "I would be lying if I said we were just good friends. I have so fallen for him - he is lovely.
"He's so hot and he's really sweet to me. When we hang out, it feels right, even though it's pretty new."
Pierce Brosnan is 'outrageously' kissable! Legendry actor Pierce Brosnan may not be attached to the 'James Bond' film series anymore, but he is still considered to be one of the most kissable men in Hollywood.
