Mary Stuart Masterson is expanding her family – by two.
The actress, 44, and husband Jeremy Davidson are expecting twins this summer. The couple are already parents to a 17-month-old son.
"We are four months along. So balancing career and family is becoming increasingly challenging for me," Davidson, who stars on Army Wives
, tells E! Online.
"And in five months we are going to have three kids under the age of 2. We are in happy shock about it."
