Mary Stuart Masterson, Jeremy Davidson pregnant with twins

Mary Stuart Masterson and hubby Jeremy Davidson are about to increase the size of their growing brood... by two!

"My family life at home in Brooklyn is becoming [more involved] -- we're actually pregnant with twins," the "Army Wives" actor tells E! online.

"We are four months along," he adds. "So balancing career and family is becoming increasingly challenging for me... and in five months we are going to have three kids under the age of two." 

The now 44-year-old "Fried Green Tomatoes" actress gave birth to the couple's first son in October, 2009. She and Davidson were wed in 2006.

The twins are due in August and according to their daddy, he and Masterson are "in happy shock about it."

Congratulations to the happy family!
