Jessica and Joe SimpsonJessica Simpson’s dad has denied reports that he’s been stalking Jessica’s ex-husband Nick Lachey.

The New York Daily News has quoted a source as saying that Joe Simpson spied on Nick and demanded access to a nightclub’s security videotapes so he could see what Nick got up to while in there.

Nick and Jessica’s divorce was finalised last month but they are rumoured to still be in the process of making a financial settlement - with Nick potentially entitled to half of Jessica’s millions.

The source said: “Joe was looking to incriminate Nick. He told the club, ‘If you ever want to see my daughter there, you’ll give me what I want.’”

The Simpson family have denied the reports.
