"Good food and great advice... Love my momma!!! #bettyknowsbest" the actress captioned the pic of the mother-daughter duo enjoying drinks (and a word or two of advice) at a beachside restaurant.
Witherspoon has never been shy about her adoration for her mom, and readily admits how she shaped her as a successful working mother of three. The Oscar winner spoke to Southern Living in August about the challenges of motherhood and how she looks to her own mom for more than just advice.
"There are some sacrifices you make, and it hurts your heart sometimes, but my kids tell me they're proud of what I've accomplished, and that just means everything," she shared. "I grew up with a working mom, and I have so much respect for the things she did as a nurse and a teacher. I would never begrudge her that."
