Tiffany Thornton, who starred on "Sonny with a Chance," lost her first husband, musician Chris Carney, in a car accident in Hot Springs, Arkansas in December 2015.
Thornton married Carney, who starred on the MTV reality series "twentyfourseven," in 2011 and the couple had two children together.
On Saturday Thornton married Arkansas worship pastor Josiah Capaci and called it the "Best day of my life" on an Instagram photo of her and her new husband.
Soon after that Thornton, 31, addressed the haters in the caption of another Instagram image of her and Capaci on their wedding day.
"This. This is love. That all encompassing, enduring, accepting, near perfect love," Thornton wrote. "The kind that trumps my need to snap back at people who have the audacity to comment on my Instagram about whether I loved my first husband or not."
She went on to say "There is no timeline for grief or for when God moves in your life in undeniable ways" and said she was extremely emotional walking down the aisle.
"I thought of Chris watching us and knowing he would have loved the choice I made, for me and for the boys," she wrote." I thought of Chris's amazing parents sitting front row and how much of a blessing they have been and will forever be in our lives."
"It wasn't my choice to fall in love so quickly after Chris passed but I was growing so comfortable with being alone that it was becoming unhealthy," she continued. "Looking back now I think God saw that if I went too long without love that it would become increasingly difficult for me to submit to the authority of a husband after being set in my own ways."
Thornton called Capaci the "greatest thing that's ever happened to me" and said her new marriage "in no way indicates that I didn't love my first husband with all that I had."
"It doesn't make you any better of a person to cast judgment on others and sit in the seat of mockers," she said. "I will always love Chris and Jo knows that. And I will always love Jo. The beautiful thing about love is that it multiplies as new blessings come into your life."
