Denise Richards and Aaron Phypers found some more mud to sling … Denise says she caught her estranged husband red-handed stealing her laptop.

The estranged couple had their lawyers duke it out in court Friday as part of a hearing for the temporary restraining order Denise has against Aaron … and Denise’s camp claimed they have security footage of Aaron running away from her home with her computer in hand.

Denise has claimed Aaron stole a laptop containing her nude photos … but Aaron’s denied it. His lawyers said Friday he doesn’t have the laptop — but her attorneys shot back with their claim that they have him on video with the laptop.

Worth noting … Denise’s attorneys did not show the alleged video — at least not in this hearing.

Aaron joined the hearing by Zoom, wearing a blue shirt and a dark blue tie — but Denise did not appear … which is interesting, because she had an apparent black eye earlier this week.

Denise previously used claims of Aaron giving her a black eye to get the TRO in the first place … he denied the allegations and said she sometimes gets drunk, falls and hurts herself. She then appeared with a black eye and a cut on her chin this week and sources close to her told us it’s just lighting and shadow giving the appearance of a black eye … and she had micro-needling and a PRP injection.
