Pop sensation Britney Spears has already started to plan her forthcoming 30th birthday and in true celebrity fashion, she revealed it will be a 'spectacular' celebration to mark the milestone occasion.

The US star will be on her Femme Fatale album tour in South America when her birthday rolls around on December 2, but she has no intention of letting her concert stop the party plans.

Spears said, "I'm really excited and will definitely do something spectacular. I'm going to be in South America so I'll have to do something pretty fun. A carnival of Britney? I don't think I'll be doing that! It'll be something a little more low-key!"
