While we patiently await more news about a possible Downton Abbey movie (*fingers crossed*), one of the series’ stars has just announced an exciting IRL romantic development: Allen Leech revealed that he’s engaged to actress Jessica Blair Herman.

The bride and groom-to-be, who have been dating since 2016, took to Instagram to share the big news with fans. “Happy Valentine’s Day @jessicablairherman,” Leech, AKA Downton‘s Tom Branson, wrote alongside a photo with Herman. “First one as a fiancé! Thank you for saying yes and for making me the happiest.”

He also clarified that he didn’t actually pop the question on Valentine’s Day, adding, “(And no I didn’t do it today. It’s been a while.) xx”

The pic he posted shows the lovebirds posing against a scenic outdoor backdrop, with the actress’ hand on Leech’s chest so we get a clear view of her engagement ring. It appears to be a single center stone on a delicate band.

Herman, whom you might have seen on American Crime Story, Fresh Off the Boat, or Modern Family, also shared a photo on her own account, of Leech giving her a kiss on the temple. “The day you proposed was one of the best days but every day with you is my favorite,” she captioned the image. “I love you! Happy Valentine’s Day @therealleech!”

Fans are thrilled by the news and have been leaving their well wishes in the comments of both posts.

We’ll add ours, too: Congratulations to the happy couple!
