Looks like they've made it official.

"Modern Family" star Sofia Vergara and "True Blood"'s Joe Manganiello are reportedly engaged, according to E! News. Although the pair have yet to make an official announcement, a source tells E! News that Manganiello popped the question on Christmas Eve at sunset.

"I've never seen two people so truly in love," says the source. "The way they talk to each other, touch each other. It's incredible."

The couple have been dating since July, shortly after Vergara broke off her engagement to Nick Loeb.
