Lindsay Lohan is the latest celeb to join the world of TikTok, and her debut has gone viral for not the reason you'd expect.

In the first short video posted to her channel, the 'Mean Girls' star introduces herself saying: "Hey everyone. It’s Lindsay Lohan, and guess what? Now I’m on TikTok."

Fans quickly spotted that the actress pronounced her name 'Lowen' instead of 'Low-han', which is the way that pretty much everyone has pronounced it as all this time.

"Wait. Lindsay ‘LOWEN'?!?!!?" one user commented. "I'VE BEEN SAYING IT WRONG MY WHOLE LIFE?!?"

Another wrote, "I'm sorry I've said your name wrong my entire life."

Another fan chimed in writing, "Have I been pronouncing your name wrong my entire life? I thought it was LoHAAN."

Yet another user said jokingly, "U pronounced ur name wrong."

Lindsay Lohan treated fans to another treat on Tiktok, calling back that other movie aside from 'Mean Girls' she's most renowned for - 'The Parent Trap'.

Speaking in an English accent, mimicking the British twin Annie that she played in the movie, she says: "Yes, you want to know the difference between us? I have class and you don’t."
