Lisa Rinna Speechless In Frontless Dress Without Bra

Scroll for the video. It comes as Lisa's 19-year-old and 21-year-old daughters Amelia and Delilah make headlines for their bikini bodies, but the Bravo star was proving she's the OG.

All in bold yellow on a shoot and in a slinky, impossibly low-cut dress with ruched fabrics and a plunging neckline, the former "Melrose Place" actress struck a figure-flaunting pose, also showing off gold jewelry and peeking her sky-high stilettos heels. Lisa, who comes with a mouth, kept silent, though. No worded caption was offered.

Adding only a box emoji showing a $ sign, the mom of two nonetheless managed to snag herself over 2,000 likes in just 45 minutes, and it looks like the video has caught the attention of a major celebrity. "Live! With Kelly and Ryan" star Kelly Ripa left a like – the blonde is a giant fan of Lisa's new lipsticks.

"You look beautiful and yellow wow," one fan replied, with another asking if Jamie Lee Curtis wore this to the Golden Globes.

If you don't live inside Lisa Rinna's Instagram, one thing has stayed the same amid the global pandemic. The legendary home dance videos are alive and well, with Lisa flaunting her massive thigh gap for the 'Gram as she continues to stay fit in lock-down.

"It’s pretty much the same every day. I get up with a prayer, and try to start the day positively by meditating. I do an exercise class at 8am," the star told Marie Claire last year. See her home spandex dance below!

Calling her Isaac Boots Torch'd workout the best thing sliced bread, Lisa added: "It’s 45 minutes of joy, and it has helped me more than anything during this quarantine time."

"Then I do a bit of work, emails, Zoom calls, interviews like this. Then I go for a walk or a hike, come back and work in the garden as we’re trying to grow one," she revealed.

That lock-down is earning Rinna big bucks, though, with her $45 Lip Kits flying off shelves. Scroll for Lisa showing why one shade is named "Birthday Suit."
