Witherspoon and Toth announced their engagement in December 2010, and they later wed in March 2011. They share 10-year-old son Tennessee, and Witherspoon also shares two kids with ex-husband Ryan Phillippe: daughter Ava, 23, and son Deacon, 19.
In July, the Big Little Lies actress shared photos of herself with Toth in honor of his birthday. She wrote in the Instagram caption, "Happy birthday to my sweet hubby, JT! Don't know anyone who loves Tour de France / road biking / @arsenal / @nashvillesc / @steelers .... oh and GOLF ... basically all sports more than YOU. Love you so much!"
She marked their 11th wedding anniversary last year on Instagram, writing at the time, "Happy Anniversary JT!! 11 years of adventures, love & laughter. I feel so lucky to share this wonderful life with you."
