This is not the first time Witherspoon has gushed about her love for Toth on Instagram. Last year, she shared a photo of Toth with their son, Tennessee, along with a sweet message about her husband.
"Every day, I'm so thankful to have this amazing man as my partner. I would not be where I am in this life if I didn't have his constant encouragement and complete support," the mother-of-three wrote. "He changes diapers, makes carpool runs and always has time to give me a much needed pep talk... He makes a really good latte too! ?."
Witherspoon married Toth on March 26, 2011, at her ranch in Ojai, California. She also has two kids from her previous marriage to Ryan Phillippe, a 16-year-old daughter Ava and 12-year-old son Deacon.
Last week, the budding producer celebrated another milestone -- her 40th birthday! In true Hollywood style, the bash was filled with A-list guests like Jennifer Anniston, Kate Hudson and Matthew McConaughey. Taylor Swift even turned up to put on a private concert for the birthday girl.
