Macaulay Culkin discovers his brother Kieran is nominated for a Golden Globe while live tweeting the show

Macaulay Culkin made an amazing discovery while live tweeting the 2019 Golden Globes on Sunday.

Upon watching the annual award show, the 38-year-old actor noticed that his younger brother, Kieran Culkin, was at the event.

"Oh sh*t! My brother is at the Golden Globes?! That is so cool! #GoldenGlobes," he wrote.

Macaulay went on to compliment his brother's looks, sharing a red carpet pic of Kieran and his wife, Jazz Charton, writing, "My brother looks so handsome at the #GoldenGlobes."

The brotherly love took a hilariously sarcastic turn when Macaulay wrote, "Oh my god, there he is! Hi bro!" alongside a pic of Henry Winkler. In a follow up tweet, the Home Alone star shared a zoomed-in look at the Henry Winkler shot, showing his brother standing in the background.

Macaulay -- who recently changed his middle name to "Macaulay Culkin" after a public vote -- continued his playful ribbing, telling his fans, "You know, if y’all voted for me to change my name to Kieran I’d be at the Golden Globes right now. Just saying. #thanks"

Macaulay went on to marvel at his little brother's good seats and request a special favor from Kieran. "Whoa! Kieran has such good seats! Dude, ask Gaga why she isn't following me on Twitter! #GoldenGlobes," he demanded.

The surprise of Kieran's attendance at the Globes was nothing compared to Macaulay's next discovery -- his brother was up for an award! The 36-year-old actor was nominated for Supporting Actor in a Series, Miniseries or Motion Picture Made for TV for his role on HBO's Succession.

"HOLY SH*T KIERAN IS NOMINATED??? WHAT IS SUCCESSION?!" Macaulay asked. "Man, I should really answer his calls more often. Thanksgiving is going to be really awkward this year. #GoldenGlobes"

Kieran ended up losing the award to A Very English Scandal's Ben Whishaw, meaning Macaulay's pick for the category -- Henry Winkler for Barry, not his brother -- lost too.

"This show is rigged!!! I was totally pulling for Winkler. #GoldenGlobes," Macaulay joked. "(No one tell [Kieran] he didn't win)"
