Simpson shares her two daughters and 7-year-old son Ace Knute with husband Eric Johnson. Last month, the couple celebrated six years of marriage together.

The Blonde Ambition star paid tribute to her husband, 40, on their special day with a sweet Instagram post.

"Eric Johnson, my Husband, I love you. 6yrs ago today I married my perfect soulmate," she wrote. "Our unity was written in God's sky of colliding stars. Together we manifest dreams, nurture desire, and hold space. Destined, it always has been and always will be, forevermore."

The "With You" singer also mentioned the special gift that the former NFL tight end presented her: a large geode crystal in the shape of a butterfly. "Also, anyone who knows me at all knows that this crystal butterfly is my dream gift 🦋," she wrote.

Simpson then finished off the post with a quote from Emily Brontë's Wuthering Heights, writing, "Whatever our souls are made of, his and mine are the same."
