Lisa Rinna turns 58 in plunging birthday swimsuit

Lisa Rinna is saying “this is 58” as she poses in a white bathing suit and stuns her 2.1 million Instagram followers. The Real Housewives of Beverly Hills star, who made headlines recently for saying she was proud to start a business at 57, was all wild hair and killer body in a selfie shared ahead of the weekend – with Lisa turning 58 years old, though, this was no regular selfie.

Lisa, who has been making headlines for partying it up as fellow Bravo face Teddi Mellencamp turns 40, showed fans that age is but a number. Erika Jayne has since topped comments with her “YES.” See why below.

Lisa Rinna Wows In Birthday Swimsuit

Scroll for the snap. Lisa, who has sparked weight concern this year and had fans thinking she was too skinny as she modeled a green bikini from Khloe Kardashian’s Good American line, was looking radiant and also low-key. The photo showed the former Melrose Place actress leaning forward and indoors as she afforded quite the view in a low-cut white one-piece, also wearing oversized and tinted ’80s shades.

Lisa, looking expressionless and also throwing out her famous pout, mentioned her age in her caption, also using a white heart emoji and kiss-face one among others. The mom of two, still dealing with 20-year-old daughter Amelia Hamlin dating 38-year-old Scott Disick, was told: “Dayummmmm” by one fan, also getting fire emoji from her Rinna Beauty brand.

The post, which gained over 80,000 likes, comes in the wake of Lisa opening up on her fitness and diet – she’s called herself a “dirty vegan.” Last year, she made headlines after telling OWN:

“I started working out at a very young age. I started playing competitive tennis, and I’ve worked out my whole life. For me, working out is like brushing my teeth.”

The star, who also told Andy Cohen that her relationship with food can be messed up by virtue of being in the Hollywood industry, did mention treats, though – but not too many. “Sometimes, I’ll have an ice cream sundae, but if I had one every day, I would feel awful,” she added.

Lisa is finding a new side to herself in her mid-to-late fiftes via her Rinna Beauty brand, one retailing $45 Lip Kits and seeing fans rush to hit buy. Lisa remains known for that iconic pout, one she has admitted is the result of a view clinic visits.
