Busy Philipps turned to the Pope after having an abortion when she was 15.

The 39-year-old actress has revealed in her upcoming memoir, 'This Will Only Hurt a Little', that she became pregnant with her first serious boyfriend and that her parents discovered the news from reading her diary.

She recalls her mother telling her: ''You're being selfish ... You're going to murder a baby.''

The former 'Dawson's Creek' star - who has daughters Birdie, 10, and Cricket, five, with her husband Marc Silverstein - explained that her mother was ultimately a supportive figure through the heartbreaking experience.

She said: ''My mother is who you want in your corner.''

Following the abortion procedure, Busy went on a trip with her school to the Vatican, where she spoke to Pope John Paul II.

The leader of the Catholic Church's words helped Busy to move past the traumatic experience.

She shared: ''I never told this story publicly ... I haven't even told people I'm very close with.

''It doesn't work for me without getting the absolution I needed. And from the only person in the world who could give it to me: the Pope in Rome.''

Meanwhile, Busy previously revealed that although she and Mark - who is a screenwriter - work in the entertainment industry, she's not sure whether she wants their children to follow them into the business.

But the actress insisted she'd be happy to support her daughters with whichever ambition they ultimately decide to pursue.

Busy said: ''The biggest thing for me as a parent is that I want my children to feel supported and loved, and I want them to pursue whatever brings them the most joy and happiness in their life, so we'll see what that is some day.''
