Name: Nikolas and Lorenzo Brino
TV Show: 7th Heaven (David and Sam Camden)

Birthday: Sept. 21
Hometown: Lancaster, CA

Returning as twin boys David and Samuel Camden, born to Eric and Annie in February 2000, the Brino quadruplets - Nikolas, Lorenzo, Zachary and Myrinda -- made their television debut on the hit series 7th Heaven.

Born in September 1998 to parents Shawn and Tony Brino, the babies were conceived through in vitro after the couple tried to have children for years. As luck would have it, Shawna and Tony attended an infertility seminar and won the raffle - a free in vitro procedure. The babies were born six weeks early and made their primetime debut when they were just over 5 months old. As the quadruplets grew older, they were given more screen time and more challenging work, such as looking at another specific cast member, smiling, crying, walking and finally, even talking. Now, Nikolas and Lorenzo handle the roles without assistance from their two siblings, but they're all still very much a part of the 7th Heaven family.

When not busy working, Nikolas and Lorenzo spend time with their family and enjoy being kids.
