Tori Spelling always thinks her husband is cheating on her.

The actress - who met spouse Dean McDermott when he was still married - admits she can't control her jealousy and regularly thinks female callers to their home are sleeping with her partner.

She said: "We're a loving couple, but were human and definitely not perfect. Given our history I often get worried that Dean is going to cheat on me. If the phone rings and it's a girl's voice I have to ask if he's having an affair."

Tori - who has two children, Liam, three, and two-year-old Stella, with the actor - admits Dean constantly reassures her that he is faithful, and though she believes him, she can't stop herself from making the accusations.

She added to People magazine: "Dean has never been anything but devoted, and he tells me over and over again that he would never do that. Deep down I believe him. But I can't stop myself. For some reason I'm compelled to accuse him of cheating.

"I apologise to Dean constantly and it drives him crazy and rightfully so."
