Marcus Smart is officially off the market.

The 28-year-old Boston Celtics guard recruited actor Will Smith to help him propose to his girlfriend, Maisa Hallum, on Christmas Day.

According to Boston25 News, Marcus created a buzz on Sunday when he tweeted: “I’ve had enough. Been holding it in too long and it’s about time this gets said…”

He followed up with another tweet: “It’s time for me to leave,” before adding, “Oh I forgot the rest… Time for me to leave the single life.”

Then on Instagram, Marcus shared a video from Will Smith, who is on an expedition in Antarctica.

In the video, Will told Maisa she may not have gotten the stuff she wanted for this Christmas, but “I promise you’re not going to end this Christmas empty-handed.”

Maisa looked confused. She turned and said, “Will Smith!?” That’s when Marcus got down on one knee and asked her to marry him.

“She said Yes!” he said, as friends and family applauded in the background.
