Denise Richards is back in town from her recent trip to Vancouver, where she was shooting scenes from her new Farrelly Brothers film, Blonde and Blonder. Denise's sudden outburst of anger towards two paps who were filming her on-set antics ended with her throwing their lap-top over a hotel balcony, where it allegedly hit two older ladies! Since Denise has been nothing but nice to us whenever we've encountered her out and about in LA, I suspect the Canuck's must have said something to provoke this sweet mother-of-two! Regardless, Denise was very well-behaved (but still dodged our questions) when we ran into her at the supermarket on Sunday.
