In the comment section, Taylor Swift herself welcomed him on TikTok and commented, "OMG!!!!" punctuated with a grinning face with star eyes emoji.

It may be his first video on the platform, but he sure knows how to use its humor already. As of writing, his video has generated nearly 85K hearts and more than 3K comments — including Taylor Swift's.
