Los Angeles, Aug 24 - Actress-singer Jessica Simpson got in touch with a woman on the Internet and attempted to put a curse on her ex-boyfriend, American football star Tony Romo.

'Jessica is normally a really sweet girl, but she still believes that Tony callously dumped her,' contactmusic.com quoted a source as saying.

'She found a woman in California. The two met at Simpson's Beverly Hills home where they lit a candle, burned some incense and performed a couple of incantations,' he added.

Simpson was dumped by the American football star the night before her 29th birthday last month and after the break up she met the woman on the Internet and paid her to put a curse on Romo to ruin his chances of falling in love again.
