Peter Dinklage and wife Erica Schmidt welcome second child

Star Peter Dinklage and his wife Erica Schmidt have welcomed their second child together.

Reportedly, the couple did not publicly confirm the pregnancy, but were spotted out with their newborn at a concert in September.

Dinklage and

Schmidt

are already parents of a five-year- old daughter, whom they welcomed in 2011.

Schmidt, 42, showed off her growing baby bump in March when she walked the carpet alongside Dinklage, 48, at the premiere of The New Group's 'All the Fine Boys,' an off-

Broadway

play she wrote and directed.
