Jinger is pushing a more expensive knockoff of the Revlon brush dryer. There is a similar knockoff on Amazon for $39, I think this brand just adds their logo and uses influencers to sell it at a supposed discounted price.
Someone definitely tipped off the paps. The woman who took the pictures posted this last year on her Instagram. She has worked for TLC before.
According to her IG, she has taken most of Jinger's papped pics.
