Lindsay Lohan gave one of her fans a very ‘Freaky Friday’ … sharing a video to TikTok wishing her a happy birthday after the fan’s mother asked Lohan for the shoutout in a viral video.

Here’s the deal … a woman on TikTok — who goes by the screen name @wends4407 — shared a clip to the popular social media site where she talked about her daughter who she says suffers from a rare genetic disorder.

Wends says her daughter — also named Lindsay — has a kind heart, always looking to be everyone’s friend despite her challenges. Her mom, who is raising her without a partner, adds she wanted to do something nice for her upcoming birthday.
