Actresses Kirstie Alley and Tawny Kitaen are locked in a nasty war of words following reports they're dating the same guy.

Kitaen, the former wife of WHITESNAKE star DAVID COVERDALE, is upset by claims Alley is after her boyfriend, stock trader RANDY OSTIN - after the ex-CHEERS star was spotted out on an apparent date with him recently.

And she is letting Alley know she's far from happy in the pages of US tabloid National Enquirer.

Kitaen spits, "I'm sure there was nothing to it... I'm very confident that Randy and I have a solid relationship.

"Randy is a very nice guy and he was probably just being very nice to Kirstie, who's, you know, a little older... I have no worries."

Alley's publicist insists Kitaen has nothing to worry about, stating, "Kirstie Alley is not dating anyone."
