The pair first met in 2006 and started dating shortly after. Their whirlwind romance was filled with sweet moments, romantic getaways, and adorable couple selfies. However, their relationship was not without its challenges. In 2008, they announced their separation, citing differences and busy schedules as the reasons for their breakup.
While the KC Concepcion rumor is false, the scandal that spawned it was very real. In 2009, Hayden Kho Jr., a Chinese-Filipino celebrity cosmetic doctor, found himself at the center of a firestorm:
In 2007, Hayden Christensen started dating actress Rachel Bilson, known for her roles in "The O.C." and "Zoolander 2." The couple had a daughter, Caia Addine Bilson-Christensen, born on November 12, 2009. Although they parted ways in 2017, they remain co-parents and maintain a cordial relationship.
Following the controversy, Kho underwent a highly publicized personal transformation. He credited his journey to Christian faith, mentorship, and a commitment to rebuilding his life.
