But does she look like her grandma?
The Real Housewives of Orange County star's eldest son Ryan and his fiancée Sarah Rodriguez welcomed their first baby girl together, Ava Ryan, who was born on February 9th and came in at a bouncing and healthy 7 lbs. 14 oz.
Now, she's sharing the first pictures of the beautiful baby. "She has her momma's eyes and her daddy's cheeks," Tamra posted on Instagram, before showing off a close-up of the newborn.
The proud grandmother also shared more special family pictures from the hospital including one with Ava and her proud new father Ryan (whom Tamra says "hasn't stopped smiling") and one featuring four generations of her family, including Tamra herself and her own mother.
Tamra has already taken her new duties as a grandma very seriously, throwing a special cowgirl-themed shower for Ryan and Sarah back in December and posting photos of recent purchases that include everything from adorable onesies to baby track suits and tiny moccasins.
"I can't wait to see the look on my son's face when his first daughter is born," Tamra previously said about becoming a grandmother. "Meeting your baby for the first time is a moment that a parent never forgets. Now I get to see it through a grandmother's eyes."
