Macaulay Culkin and Brenda Song have gotten engaged

"Happy 40th birthday to this magical being," she wrote in the caption. "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. https://www.instagram.com/p/CWBxGZuhut2/?utm_source=ig_embed "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." Macaulay also opened up about his plans to spend his life with the Suite Life of Zack and Cody actress on The Joe Rogan podcast. "This one’s a good one, so I’m probably going to put some babies in her," he joked. He went on to say: "I have a pretty little family - a pretty girl, a pretty dog, a pretty cat and all that stuff." The Home Alone actor was previously married to Rachel Miner from 1998 to 2002. This will be Brenda's first marriage.
