EXCLUSIVE
“Teen Mom” Catelynn Lowell got a personal invite to Sia‘s Detroit concert after the singer reached out to her … she says because they have something dark in common.
We got Catelynn at LAX where she told us Sia was a fangirl of “Teen Mom” and singled her out on social media with the invite.
It’s not the first time Sia’s been motivated to help … she gave an animal loving “Survivor” contestant $100k after he refused to kill his chicken.
Catelynn didn’t get any cash but Sia did make it worth her while. #cheapthrills
