Don't knock it 'til you've tried it.
During Wednesday night's episode of "Watch What Happens Live" when Andy Cohen asked "Paint it Black" star Amber Tamblyn about the backlash over her husband David Cross drinking her breast milk, the new mom made Cohen an offer he couldn't refuse.
"I pumped when I got here earlier 'cause I came from work," Tamblyn said as she whipped out a bottle of her breast milk. "Do you want me to make you a White Russian?"
Tamblyn and fellow "Watch What Happens Live" guest Tinsley Mortimer from "The Real Housewives of New York" chanted "chug, chug, chug, chug" as Cohen took a hefty sip of Tamblyn's milk.
Cohen winced heavily but admitted it was "very sweet."
"That's the closest to a breast I've ever been," he joked.
Tamblyn said she's tried Blake Lively's breast milk, which meant Cohen has technically also drank Blake Lively's breast milk.
Must be a "Sisterhood of the Traveling Pants" thing.
"So does that mean I've done it with Ryan Reynolds?" Cohen asked. "Because that would make it all better."
