Apparently, Real Housewives of Beverly Hills' Brandi Glanville's ex-husband Eddie Cibrian was losing his hair  but that's not all he lost.

Radar Online is revealing a new excerpt from Brandi's upcoming book, Drinking and Tweeting, in which Brandi describes an unfortunate side effect to Eddie's hair-loss medication. 

“Eddie had started taking Propecia, like many men, because he was concerned about hair loss,” Brandi writes. “He had fantastic hair, but who was I to sideline his vanity?”

But Propecia had a pretty big downside, as it apparently made him impotent.

“This particular drug had nasty side effects — including ones that happened in the bedroom," she reveals.

“I knew he was concerned about his hairline, but momma needed something h**d," Brandi shockingly continues. "I was not down for a limp d**k and gave him an ultimatum: It was the Propecia or me!” Wow. Just wow.

Eddie responded by insulting her lady parts in a "vulgar" way, which apparently led to Brandi eventually getting vaginal rejuvenation surgery on his dime.

So if you were worried that Brandi's love life wouldn't have enough juicy details to full a whole book, fear not.

In fact, we almost want to erect a statue in Brandi's honor to thank her for all these wild stories. (Get it — "erect"?)
