Erika Girardi Posted a Baby Photo to Mark Turning 50

Erika Girardi and Lisa Rinna each celebrated birthdays recently — and both of The Real Housewives of Beverly Hills cast members marked another trip around the sun by posting adorable throwback photos on Instagram.

Erika's birthday was particularly noteworthy, as she turned 50 this past weekend. She shared a rare vintage photo of herself as a baby and captioned the sweet photo, "Welp, I[']m 50!"

The snapshot didn't go unnoticed as Lisa, Dorit Kemsley, Kyle Richards, Kathy Hilton, RHOBH alum Eileen Davidson, The Real Housewives of Atlanta's Cynthia Bailey and Kandi Burruss, as well as The Real Housewives of New Jersey's Dolores Catania all posted comments, among others. Teddi Mellencamp Arroyave, who recently celebrated turning 40, also left several heart emojis in the comments.

Erika also posted a photo of her dog Tiago napping in bed with a nod to her landmark birthday in the caption: "This is 50."

Erika also took some time out of her birthday weekend to wish Lisa a happy birthday as well. Her caption alongside a video montage of her friendship with Lisa read, "We have laughed and traveled the world together making some incredible memories!!! So happy for alll your success!! More to come!!!"

The two birthday girl besties also commented "I love you" to one another in the comments. And elsewhere, Lisa shared a sweet message for Erika featuring an inside joke between the ladies: "Happy 50th Birthday Thelma!"

And that brings us to Lisa's birthday. Like Erika, she posted a sweet throwback photo from when she was a kid with the caption, "Some things never change. It’s my birthday. I’m going to party like it’s my birthday." Her throwback image got comments from Erika, Dorit, Teddi, Crystal Kung Minkoff, and Kathy, among others.
