Gamboa introduced him to his manager, Jhun Reyes, who brought him to ABS-CBN for the first season of Pinoy Big Brother: Teen Edition.
Anderson and the other housemates entered the Big Brother house on April 23, 2006.
After 42 days, he was named Teen Third Big Placer on the show.
While she did not directly mention Anderson, Geronimo confirmed that she is still hurting because of another failed romance.
She previously had a secret relationship with actor-dancer Rayver Cruz, who decided to move on because he could no longer "wait" for the Kapamilya singer.
He also has a younger brother (Kenneth Anderson) and two older sisters from his mother's first marriage.
When he was three years old, he and his family moved from General Santos City to San Antonio, Texas, and then to Springfield, Missouri, when he was six.
As of December 2015, he has been nominated for 21 acting nominations, he won 10 Best Actor awards and 1 Supporting actor award.
