The Interview star posted a photo of Dave and the former Mad Men actress, who have been dating for three years, walking hand-in-hand on Instagram.

“Congrats Davy and Allison!!! engaged!!!” he wrote as a caption. “I WUUUUUV YOU.”

Brie had confirmed the engagement by showing up to her Sleeping With Other People premiere on Monday wearing an engagement ring. Meanwhile, Franco was seen celebrating their engagement with friends at Sushi Park in Los Angeles while Brie attended her premiere.

Brie must’ve fallen hard for Franco, because she suggested she wasn’t the “marrying kind” in the past, before she even started dating him. She did say, “Maybe I just haven’t met the right guy yet — that’s the flip side.”
