After news broke that George Michael died "peacefully" in his home at the age of 53, celebrities took to Twitter to share their reactions.
One celebrity was '90s icon Sarah Michelle Gellar. However, fans quickly noticed something wrong with what she posted.
On Sunday night, Gellar tweeted, "Do you really want to hurt me? I guess you do 2016 #ripboygeorge.”
Do you really want to hurt me? I guess you do 2016 #ripboygeorge.
55-year-old singer Boy George is alive and well. The "Karma Chameleon" performer also rose to prominence in the late '80s and '90s, and was known for his flamboyant looks and dramatic eye makeup.
Maybe this mistake wouldn't be so bad if it didn't have such a "All '80s gay male icons are the same" type of vibe.
Gellar has sine deleted the original tweet, but Twitter immediately fired back, prompting her to respond in a series of messages.
Gellar's Twitter account is mostly full of pictures, and she expressed immediate regret at making a comment at all, saying,
"This is usually why I don't comment on public matters, but it all seemed so sad on Christmas. Lesson learned."
"For the record, yes I completely know the difference between Boy George and George Michael -- I heard incorrectly. My intentions were good."
She thanked Twitter for correcting her, adding "it's still so sad."
Gellar's social media tributes haven't always flopped.
Last year, during the one-year anniversary of Robin Williams' death, Gellar posted a touching tribute that displayed the infamous bench he sat on while acting in "Good Will Hunting" with a powerful Ralph Waldo Emerson quote.
SMG and Robin Williams were costars on the CBS show, "The Crazy Ones," which was cancelled after one season.
Gellar made an honest mistake, but in the age of Twitter, no mistake ever truly goes unnoticed.
RIP George Michael, a true legend and pioneer in the music industry.
