CHER'S HEAD GAMES WITH SONNY'S WIDOW

Fight over $1M music royalties gets personal

POP icon Cher is deliberately twisting rival Mary Bono's tail by insisting she was the love of their mutual hubby Sonny Bono's life as part of all-out psychological warfare over $1 million in music royalties, insiders tattle.

With Bono's widow and ex-wife ready to square off in court this year, sources say the rock diva is turning the knife, hoping to get an upper hand in the messy money battle, which began two years ago when Mary, as the head of her hubby's estate, stopped sharing royalties earned on Sonny and Cher classics.
