Olivia and Ava White (born June 24, 2005) began acting when they were only 10 weeks old, guest starring on Veronica Mars and Ghost Whisperer.
At the age of 6 months, they landed the recurring role of Claire Kiriakis on the NBC soap Days of Our Lives.
The girls also held the recurring role of Carrie Greco in the ABC prime time show What About Brian during its second and final season.

Watch out, Olsen Twins.
