The announcement - in the form of a heart emoji - went straight to the heart of the matter.
On Wednesday (Dec 4), Dave McCary, 34, posted that he and actress Emma Stone, 31, are now engaged.
He also shared a photo of the happy couple, with Stone revealing her new ring.
McCary, who is a segment director and writer for American comedy show Saturday Night Live (SNL), and Stone have dated for two years.
They met when the Oscar-winning actress hosted SNL at end-2016 and starred in a sketch directed by McCary.
Stone split up with Spider-Man actor Andrew Garfield, 36, in 2015 after a four-year relationship.
Last year, in an interview with Elle magazine, she said marriage and motherhood were on her mind.
"My perspective about kids has changed as I've got older. I never babysat or anything.
"As a teenager, I was, like, I'm never getting married, I'm never having kids.
"And then I got older and I was, like, I really want to get married, I really want to have kids."
Stone, who won a Best Actress Oscar for La La Land in 2017, is currently filming a live-action reboot of Disney's 1996 animated classic 101 Dalmatians.
