Watch Jessica Simpson's Entourage Debut

Is Jessica Simpson ready for a new furry friend? If you ask Entourage's Ari Gold (Jeremy Piven), the answer is yes.

On Simpson's Aug. 1 episode of the HBO series, Piven's character tries to improve her mood after her beloved Malti-poo, Daisy, went missing and was presumed dead.

"I know how devastated you were after losing Daisy, so I thought little Rose here would ease the pain," Piven's Ari tells Simpson, 29, who appears as herself in the clip. (Watch above)

"You really are an a--hole! Have you ever had a dog, Ari? You should know they're not like cars -- you don't just replace them...And Daisy was a Malti-poo...that's just a poo," she snipes as she slams the door in his face.

Simpson says she enjoyed her time on set.

"I have the utmost respect for the entire cast and crew of Entourage!" she Twittered after shooting the scene last May. "Thank you for making the past 2 days memorable."

Simpson's episode of Entourage airs Aug. 1 at 10:30 p.m./ET on HBO.
