Macaulay Culkin and Brenda Song were spotted holding hands on a date last week.
"Parkgoers said they were very cute with each other, holding hands and very affectionate," a source said. "Looked like they were having a great time."
Culkin and Song appeared to be on a double date with actor Seth Green and his wife, Clare Grant.
Culkin and Song star in Green's forthcoming directorial debut, "Changeland."
"They all looked super comfortable together and like they were having a great night out," an insider said.
Us Weekly confirmed the news Monday, with a source saying Culkin and Song "were spotted holding hands and being cute with each other."
Culkin and Song were first linked in July after they were seen at dinner in Los Angeles. The actress shared a photo with Culkin and Green on Instagram the next month.
"Epic first #summerslam! Shout out to @sethgreen (aka the king of group selfies) for this amazing night and epic selfie. Haha," she captioned the picture.
Culkin is known for starring in the "Home Alone" movies, while Song played London Tipton in the Disney Channel series "The Suite Life of Zack and Cody" and "The Suite Life on Deck."
