Even though rehashing feuds can be exhausting, Kyle Richards couldn't stop herself from smiling at the taping of The Real Housewives of Beverly Hills Season 8 Reunion.

Sharing a snap of herself getting ready backstage on March 27, the mom of three said through grins: "I am showing off my new smile. Even though today's not really a day of smiling, I can't help myself." And, Kyle was quick to tag Dr. Michael Apa in her comments. 

The RHOBH pal has been working with the New York-based cosmetic dentist since early March. During a visit to the Big Apple, Kyle shared a post that explained her decision to meet with the celebrity doc. (Fun fact: his other clients have included Uma Thurman and Mary-Kate and Ashley Olsen.) 

In the March 4 post, Kyle wrote: "After hearing about [Dr. Apa] I started following him on Instagram & loved his work. After doing my research I knew I would be in the best hands with Dr. Apa." She added: "If you look through my Instagram you’ll see I always smile with my mouth closed. No, my teeth weren’t bad. But they were smaller and didn’t show enough when I smiled and it bothered me. Will show the after pictures soon." 

Sticking to her word, Kyle did show off her brand new veneers in her March 27 Instagram stories. Take a look at her bright new smile, below!

Looking gorgeous as always, Kyle!
