Salenger also shared a collage of photos from the sweet proposal on her Instagram Thursday, writing, “It’s official. I’m the luckiest happiest girl in the universe!!!! I love you @pattonoswalt I love you Alice Oswalt! #YesYesYes”

And, ever the funnyman, Oswalt joked of the proposal on Twitter: “I put the ring in a marzipan Slave I replica and said, ‘Will you be my Padawan of Love?’ She maced me but said yes later.”

Oswalt, 48, and Salenger, 47, went public with their budding romance last month at the Los Angeles premiere of the movie Baby Driver.

The couple’s happy news comes just 15 months after Oswalt’s wife Michelle McNamara died unexpectedly in her sleep in April 2016, leaving the comedian to care for their 8-year-old daughter, Alice Rigney.

Oswalt has been open and honest about the grief he’s experienced since, but judging by the happy posts on both his and Salenger’s Twitter and Instagram feeds, their relationship seems to have had a very positive impact on them both.

Although they have been dating only a few months, they are not shy about showing their affection for one another in Instagram posts and frequent interactions on Twitter.

A source close to the couple told PEOPLE their romance was “new and they’re very happy.”

“They met through mutual friend Martha Plimpton,” the insider said. “They started chatting as friends and it blossomed from there.”

The couple has been sending signals about their intentions in the last week, with Oswalt quipping over the weekend, “Aw, it’s like we’re already married!” after Salenger razzed him on Twitter.

And Salenger hinted at their engagement on Instagram Wednesday, writing, “Once upon a time… in 2008… at my friend’s wedding… I caught the bouquet… #fairytalesdoexist.”
