N-Dubz star has operation 'to save voice'

N-Dubz singer Tulisa has undergone an operation to remove a lump in her nose.

The 21-year-old singer, who discovered the problem during a routine check-up in November, was put under general anaesthetic at London's Cromwell Hospital.

"Tulisa couldn't take the risk of leaving the lump there but she was nervous that the procedure itself could harm her voice. It seems she's fine," a source told The Sun.

Writing on her Twitter page before going into hospital, she said: "Guna b in for 8 hours! Guna b a serious sleep! I hate needles, Id rather b punched in da face!"

"Wen I wake up I want nandos, my martina cole book & my ds sittin infront of me! & a BIG capri sun!"

She later added: "Haha doc is givin me valium 2 calm me down cus of my heart palpitations!

"Ok valium kickin in now time for me 2 rest, da place is spinnin."

Tulisa yesterday defended herself over a number of abusive messages she sent on the social networking site.
