Jennifer Aniston is on an Instagram roll.

The Friends star only joined the platform on Tuesday well, officially at least, given that she had a secret account all along and has already broken a world record while amassing more than 13.5 million followers.

On Thursday, she went back in time with an adorable throwback post.

She shared a picture of herself wearing a hat as a young child alongside a more recent one of her donning similar headwear for InStyle magazine .
