Brenda Song’s ring finger is shining a little more!

Song attended her Dollface costar Kat Dennings’ wedding on Nov. 27. During the celebration, the Disney Channel alum was spotted wearing what appears to be a wedding band alongside her engagement ring from Macaulay Culkin.

The Social Network actress’ new piece of jewelry appears to be a wishbone ring encrusted with diamonds across the band.

Reps for the couple did not immediately respond to PEOPLE’s request for comment.

The couple has been together for five years and a source confirmed with PEOPLE that the two were engaged at the start of last year.

Song was first photographed with the diamond engagement ring on her left hand while out and about in Beverly Hills, California, in January 2022.

The pair welcomed their first child, Dakota Song Culkin, on April 5, 2021. Less than two years later, Brenda gave birth to their second son, whose name has not been confirmed, Macaulay’s brother, Kieran, confirmed at the time.

“Macaulay and Brenda have loved being together as a family since welcoming Dakota,” a source told PEOPLE. “The engagement is the natural next step for them. They are excited for their future together.”

The couple first met on the set of Changeland in Thailand and were first romantically linked when they were spotted out in July 2017 grabbing dinner at Craig’s, an Italian restaurant in Los Angeles.

The next month, Song posted a group photo to Instagram in which she posed alongside Culkin.

Before the couple welcomed their second child, Song about her upcoming nuptials, saying, “Wedding planning is so expensive and it takes up so much time.”

She also pointed out that organizing the event as a parent is “really hard because it’s all about priorities.”

The couple also spoke to Esquire in February 2020 and Song revealed what she finds attractive about Culkin.

“People don’t realize how incredibly kind and loyal and sweet and smart he is,” she said.

“Truly what makes Mack so special is that he is so unapologetically Mack.”

She continued, “He knows who he is, and he’s 100 percent okay with that. And that to me is an incredibly sexy quality.”

More recently, the couple was seen together with their two sons at Culkin’s Hollywood Walk of Fame Ceremony.

During the ceremony, Culkin shouted out his fianceé and their two boys during his acceptance speech, thanking them for their support. “I’d like to thank Brenda. You’re absolutely everything,” he said.
