Lisa Rinna Sizzles In Purple Bikini In Throwback Beach Snap With Harry Hamlin

Lisa Rinna was in a throwback mood on Thursday, teasing her 2.9 million Instagram followers with a bikini photo that showed off her incredibly toned figure. Check it out below!

The Real Housewives of Beverly Hills star used Instagram's popular hashtag "tbt" (throwback Thursday) to post a snapshot from a previous beach trip she took with her husband, Harry Hamlin.

The 58-year-old reality star and the 69-year-old actor were seen strolling on the beach in matching outfits.

Rinna wore a two-piece bathing suit in a striking purple shade that was seemingly made of shiny lycra fabric. Her bikini top was cut in a classic triangle shape with spaghetti straps that went around her neck. The triangles were on the smaller side, showing off quite a bit of her ample cleavage. The lining was also not as thick, but the garment still managed to cover the vital bits.

The sexy mother of two coupled her top with a pair of matching bottoms that featured similarly thin straps. The sides sat high on Rinna's frame, helping accentuate her lean figure and small waistline. Her swimwear featured a low front that helped showcased her popping abs.

Rinna also rocked a pair of camouflage shorts, which she unbuttoned to show off her thong. She sported a straw cowgirl hat and sunglasses with metal frames.

Hamlin, on the other hand, wore a plum polo shirt and green cargo shorts. Like Rinna, he too wore eye protection and a colorful shawl over his neck, which probably belonged to his wife.

The couple held hands as they walked barefoot on the shoreline. The sky and the blue water coming up to shore filled the background of the shot.

"#tbt Mom and Dad. 🌊☀️🏝" Rinna captioned the post.

Unsurprisingly, Rinna's fans loved the post, and the photo garnered more than 30,500 likes in just an hour after posting. The new share also earned over 370 comments in the same time frame with admirers flocking to the comments section to share their admiration for the couple, using the opportunity to shower them with messages and emojis.

"Sheesh! The hotness in this photo. @lisarinna looking great too," a fan wrote.

"You look exactly the same ageless! Both of you," gushed another commenter.

"You should be the sexiest couple in People," noted a third follower.

Other Instagram users were admiring Rinna's body, especially her chiseled midsection.

"Ab goals. You're so beautiful," one stated, adding a trail of fire emojis.

"Serving BODY!!!!" added another.

Rinna and Hamlin, who share two daughters, Delilah, 23, and Amelia, 20, have been together for 24 years. According to E! News, the pair had their first date in 1993 at a restaurant where a waiter apparently told them they were soul mates. They got married in 1997 in front of 150 guests in the backyard of their Hollywood Hills home.

Today, they are still pretty much in love, as seen on the episodes of RHOBH and Rinna's Instagram posts.
