The couple confirmed their engagement in September 2016 and will welcome their first child later this year.
Congratulations are in order for Thomas Sadoski and Amanda Seyfried.
Sadoski has let slip that he and Seyfried, who is currently pregnant with their first child, secretly tied the knot.
The Wild actor told James Corden on the Late Late Show that the pair wed over the weekend.
“We eloped... we just took off into the country with an officiant and just the two of us, and we did our thing… We had a great day. It was perfect," the 40-year-old said.
The actor proudly showed off his wedding band, whilst revealed he and Seyfried, 31, wrote their own vows.
There was also one very special guest in attendance; Seyfried's dog, Finn.
“I know that you guys are close friends, and I know that she would want you to know, so don’t tell anyone," Sadoski joked to Corden.
