Erika Jayne posts throwback topless modeling photo

Erika Jayne has always been a star.

The “Real Housewives of Beverly Hills” star, 49, was a model and a go-go dancer before she hit it big on Bravo, and she’s got the throwback photos to prove it.

On Tuesday, the “XXPEN$IVE” singer posted a black-and-white topless snap on Instagram with the caption, “Ahhh 18…”

“The Real Housewives of Atlanta” star Cynthia Bailey said the pic was “beautiful,” while “Selling Sunset” star Christine Quinn remarked, “Omg you look exactly the same!”

Some fans even compared the young Erika to Gigi Hadid — daughter of fellow former “RHOBH” star Yolanda Hadid — and Drew Barrymore.

Erika is no stranger to a sexy photoshoot. Just last week, the sizzling star posted another black-and-white topless photo — this time from the present day.

One thing’s for sure: As she sings, looking this good doesn’t come for free.
