Congratulations are in order for Armie Hammer and his wife, Elizabeth Chambers. Right before the premiere of the actor's new movie Free Fire on Thursday, Hammer took to Instagram to share the news of another big "premiere": He and his wife are expecting their second child together!

The Man from U.N.C.L.E. star posted a seriously cute baby announcement from Canada. "Ready to start the #torontointernationalfilmfestival festivities... All three of us!" the grinning dad of one wrote alongside a photo of him and his wife looking ecstatic and dressed to the nines for the Toronto Film Festival. In the sweet shot, the 30-year-old—who looks dapper in a classic blue suit—cradles his wife's tiny baby bump, which she chose to accentuate with a skintight long-sleeved white dress for the evening.

Chambers, 34, also took to Twitter and Instagram to share the adorable couple photo. "Dressed and ready for the premiere of #Freefire. And the premiere of baby Hammer Number 2!" she wrote in her caption.

The duo is already parents to soon-to-be 2-year-old daughter Harper, and it looks like they couldn't be more excited for a second addition to the family.
