Less than a year after welcoming their first child together, Disney alum Brenda Song and Home Alone star Macaulay Culkin are engaged!

Brenda Song, known for her portrayal of London Tipton in The Suite Life of Zack & Cody, confirmed the engagement news after being photographed stepping out in Beverly Hills on Monday, displaying a gorgeous diamond ring on her left hand.

The famous actors began dating four years ago, after meeting on the set of the movie Changeland in 2017.

The pair was first linked to one another in July 2017, after they were seen grabbing dinner at Craig's, an Italian Restaurant in LA. Dating rumors began to swirl soon after, as the couple were spotted out together again, this time holding hands at Knott's Scary Farm in October.

A year later Culkin made an appearance on the Joe Rogan Experience podcast and opened up about his relationship with the actress.

"This one's a good one, so I'm probably going to put some babies in her in a little bit."

Sure enough he did. In April of last year, Song, 33, and Culkin, 41 welcomed their first son Dakota, named in honor of Culkin's late sister Dakota.

The couple who remains relatively private about their relationship on social media, kept Song's pregnancy out of the public eye as well. They confirmed the arrival of their baby boy in a brief statement saying, "We're overjoyed."

While the actress has not featured her son on social media, she did reference him in a recent Instagram post at a Rams game with Culkin. She captioned the picture of the pair with the mascot,

"Very few things can get us out of the house and away from our son."

Although the couple does not often post about their relationship, Song gushed over her fiance in a sweet Instagram post for his 40th birthday in August 2020.

She wrote, "Happy 40th birthday to this magical being. I could sit here and write endlessly about how wonderful, kind, loving, genuine, loyal, honest, brilliant and hilarious you are, and how grateful I am that I get to share and do this life thing with you. But firstly, that would take me an eternity and secondly, you won’t even see this because you don’t ever use instagram. Hahaha. My unicorn that I never thought could exist, I am luckiest person in the world because I am loved by you."
