Lisa Rinna drops jaws with sexy selfie in sheer bra

Lisa Rinna is back at it!

The "Real Housewives of Beverly Hills" star took to Instagram on Thursday to share a photo of herself wearing just a sheer bra and matching underwear, and she looks absolutely incredible.

Rina, 54, put her age-defying physique firmly on display in the mirror selfie, which appears to have been taken after a shower, as the star still has wet, slicked-back hair in the snap.

"It was time," she captioned the shot along with a emoji with its tongue sticking out.

The QVC regular garnered praise from her fans in the comments of the post, too. People were quick to praise her "fabulous" body and overall "perfection."

"Rock it Lisa, girl power!!" one user wrote.

"Lisa is a boss b--ch who can dress and look how she damn well pleases," another posted.

This isn't the first time that Rinna has flaunted her fit bod on Instagram, either. Earlier this year, she posted a completely naked selfie -- taken in the same mirror, no less -- that garnered a divisive reaction from people online. Clearly, the unapologetic star didn't let the criticism affect her!

See Lisa Rinna's nude shot in the gallery below:

So honored to have been photographed by Mert and Marcus for their book new book! 20 years in the making! It's out Sept 7th #mertandmarcus @mertalas @macpiggott #taschen
Cheers to @playboy for going back to nudes. The female body is so beautiful, every size and every age. Be proud! #thefemalebodyisbeautiful #allshapesandsizes #loveyourself #loveyourbody
Hot dog dog. Thanks for chiming in on what you feel I deserve to be paid. I believe women deserve equal pay. However I don't believe I deserve equal pay to Chris and Dave. They are legends and 2 of the greatest comics of all time. I would like to say that I have been selling out arenas these last couple years. Something a female comic has never done. That's a big deal to me, especially because I know I do my best every night on stage for the audience and they have a good time. I didn't ask for the same as my friends. I did ask for more than the initial offer. I will continue to work my ass off and be the best performer I can be. The reports of me "demanding" or "insisting" on equal pay to them aren't a true. #fat #stealsjokes
#54 and clean. Thanks for the birthday wishes!

Mikey made me do it ... Miami nights πŸ™ŒπŸ» 1. This is my pre DWTS bodyπŸ¦„ 2. I am not currently in Miami but am in NYC 3. I posted this knowing most of you would be judgmental and couldn't resist a chance to tear me down and I was right. 4. Go be offended at your own life. 5. I'm living my life to the fullest. ❀️
Just wanted to share that one of the reasons @eatingboys has inspired me so much is because of the way she mixes her humor and sexuality. I spent so many years loving my body but thinking it wasn't lovable by others- its sole purpose was to be fodder for jokes. I performed the insult so no one else could. I don't regret any of it- that's my art and that was my truth- but now, at age 31, having been through hell and back with my health and other people's perceptions of my physicality, I feel deeply comfortable with the idea that this pear-shaped pot of honey is equally good for making people laugh and laying out like a Suicide Girl circa 2004. Love it all.
