Adrian Grenier Reacts to Penis Comment in Former Bachelor Winner's Tell-All: I'm Glad She Got the Size Right

The Entourage actor was described as having "the biggest dick" she had ever seen

Adrian Grenier may not be kissing and telling, but he wasn't mad when a former flame did. 

According to a new tell-all book called I Didn't Come Here to Make Friends penned by former Bachelor winner, Courtney Robertson, she and the Entourage star hooked up. As the Arizona model described in the memoir, she was impressed with the size of the"‘sweet but non-committal" actor's—ahem—goods. 

"She said you had the biggest dick she's ever seen," Andy Cohen recalled during an interview on Watch What Happens Live. 

"I was just glad she got the size right," Adrian cooly quipped back. "And she's seen a couple of them, huh."

While other private stars may have been embarrassed by the exposure, the 40-year-old hunk took the comment in stride. 

"You're always on the edge of your seat waiting for something bad to be revealed about you and then every once in a while, it's not so bad," he explained about the surprising upside to fame.

In a subsequent blast from the past, Cohen question the actor about his appearance in Britney Spear's "(You Drive Me) Crazy" music video back in the '90s. 

Though Grenier admitted there weren't many particularly memorable moments from the shoot, he did recall Brit having "a lot of handlers."

Adrian did reveal how he had only agreed to star in the video if he could interview Spears for his own documentary. "It's called Shot in the Dark and I went to find my estranged father," he said of the project. "[Britney] has father issues."
