We feel your pain, Jen! Jennifer Garner totally nailed a funny and heartfelt rendition of the hilarious (and NSFW) children's book Go the F--k to Sleep during a video clip for Vanity Fair magazine.

Evidently digging deep to use all the hours of bedtime frustrations she's racked up in the past decade of being a parent, Garner reads the story with all the skill and devotion of a loving mom-of-three.

And as she progresses though the tale, besieged by protestations that the fictional child in the book needs one last drink, or a trip to the bathroom, it's clear from the tone in her voice that the hands-on mom has walked this path many times before!

Putting feeling and emotion into the video, which was an added extra to her recent, revealing interview for Vanity Fair, Garner remains straight faced for the duration of the clip, right up until the end when she collapses in giggles.

During her interview with the magazine, Garner talked about her heartbreaking split from Ben Affleck for the first time, and revealed that she had no regrets although her marriage didn't turn out the way she had hoped.

"He’s the love of my life. What am I going to do about that?" the 43-year-old actress asked the magazine. "He’s the most brilliant person in any room, the most charismatic, the most generous. He’s just a complicated guy. I always say, ‘When his sun shines on you, you feel it.’ But when the sun is shining elsewhere, it’s cold. He can cast quite a shadow.”
