The "Burn" singer turns 29 the day before New Year's Eve and plans to go all out for a bash although she feels exhausted from her intense promotional schedule this year, reported Contactmusic.
"I am actually having a party. Somebody was saying, 'Surely you just want to relax after everything that's been going on on your birthday'. I was like 'No'.
"I want a really huge bombastic party, I want everyone there. I want it to be like the day of me! Bring it on. I've hired a house, we're having a big party, fireworks and everything," she said.
