Justin Bieber's mom, Pattie Mallette, was told to abort her baby at age 17.
But when she became pregnant with the now famous teen singer, she didn't hesitate about keeping her son.
"I just knew I couldn't," she said in an interview with Today's Kathie Lee Gifford. "I just know I had to keep him."
Even though she didn't know how she was going to raise him, Mallette was determined not to abort her baby and to do "whatever it took."
Mallette was at the "Today" show to promote her new book, Nowhere But Up: The Story of Justin Bieber's Mom. In the book, she shares for the first time in detail her past as a victim of sexual abuse and abandonment. She also suffered severe depression as a teen and struggled as a single mom. But she clung to her faith through the dark times, a promo for the book states.
"It doesn't matter where you find yourself today – broken, hurting, wounded, or shamed. If God can help me find my way up, I promise, He can do the same for you," she says.
Her famous son, Justin Bieber, wrote the foreword to the autobiography. Bieber, 18, was named by Forbes this year as the third most powerful celebrity in the world. The Canadian-born singer has sold over 12 million albums since 2009 and has more than 27 million Twitter followers.
Mallette told Gifford that when she heard her son's first cry, "he sounded like he was singing." The full "Today" interview airs Sept. 18 and 19.
