Michael Whiteacre [pictured] and Shelley Lubben’s husband Garrett Lubben got into a crossfire Sunday afternoon in Hollywood.

Shelley Lubben was attending a Pet Adoption event when Whiteacre showed up wearing a “Shelley Lubben Treats Porn Stars Like Animals” shirt. [Others in attendance at the event included Ron Jeremy, Mary Carey, Kiki Daire, Danny Wylde, Guy DiSilva, Alex Chance, and former Penthouse Pet/ radio personality Sam Phillips.]

Garret Lubben is convinced that Whiteacre is in love with his wife. [For real.] I don’t know how he’d get that impression from the t-shirt. And Whiteacre is convinced that Lubben makes money aimed for former porn stars trying to get on their feet magically disappear through the Pink Cross Foundation.

Several people were shooting video of the exchange and something will probably show up on YouTube.
