The Big Little Lies actress, 41, posted a sunset photo with her hubby and captioned it, “Six years ago I was lucky enough to marry this wonderful man.”
She added, “He makes me laugh everyday and supports me in everything I do. Happy anniversary Jt. Here’s to many more!”
Witherspoon married the talent agent at her 6-acre ranch in Ojai, California, in 2011, and they welcomed their son, Tennessee, now 4, a year and a half later.
The actress had a week of celebrations, since she rang in her birthday just a few days before her anniversary.
She celebrated her 41st with her two children from her marriage to Ryan Phillippe, Ava, 17 and Deacon, 13.
Witherspoon posted a photo of the trio enjoying dinner together on March 23.
“There’s nothing better than celebrating my birthday with my wonderful kids!” she wrote alongside the happy snap. “#ProudMom.”
Witherspoon recently opened up to Vanity Fair about her relationship with her teenage daughter and said, “She’s a beautiful person inside and out. She’s just a good soul.”
She continued, “I really have a rich, personal relationship with my daughter.”
Ava clearly feels the same since she posted a happy birthday message to her mom too and called her one of her “best friends.”
