Throwback Thursday came a day early for Erika Jayne.

The “Real Housewives of Beverly Hills” star, 49, worked as a model and dancer in her younger life and reminded fans of the fact when she shared a topless photo on Instagram on Wednesday.

“Ahhh… 18,” Jayne captioned the black-and-white image of herself donning denim jeans and sporting long blonde locks – her arms crossed to cover her chest.

Jayne received a number of celebrity comparisons and one fan said they had to do a double-take at first glance.
