Georgia Moffett-Tennant (mother)

Date of birth: December 25, 1984

The angel-faced actor Ty Tennant inherited his godlike look from his mother, Georgia Moffett-Tennant. By the way, Ty’s mom can serve as a role model to many women worldwide.

She was born in a family of 2 actors, Peter Moffett (stage moniker – Peter Davidson) and Sandra Dickinson. Her parents separated when Georgia was 10 years old. After that, her dad re-married Elizabeth Morton, the writer, and actress. On the paternal side, Georgia has 2 half-brothers: Louis and Joel.

Georgia debuted as an actress at the age of 15. She appeared in 4 episodes of the series “Peak Practice”. At the age of 16, she discovered that she was pregnant with Ty. At first, she was afraid to tell her parents about teen pregnancy. She was in the 2nd trimester when she finally decided to share the baby news with her mom and dad. Both were shocked but supported her.

Ty’s mom is a strong and optimistic person. She cared about her baby son and at the same time knew that she was going to become an actress. “The baby is not an obstacle in my dream to become an actress”, she said once in her interview.

When Ty became a little older, Georgia returned to her profession. Her most popular screen works are “Tom Brown’s Schooldays”, “Staged”, “Doctor Who” etc.

In 2008 she met the actor David Tennant at Doctor Who set. They fell in love and tied the knot in 2011. With David, she welcomed 4 more kids.
