Our thoughts are with Tiffany Thornton at this time. The Sonny With a Chance star wrote a heartbreaking message on Instagram, honoring her friend, Brittany Blanton, who tragically passed away. Brittany was one of Tiffany's bridesmaids in her wedding.

"I keep thinking this can't be real. One of my very best friends is gone and the place she holds in my heart will never be filled. Brittany was one of the coolest people I've ever known, filled with the loudest and most contagious laughter, a huge heart, a beautiful smile and an unbelievable faith in others that not a lot of people have," she wrote.

I keep thinking this can't be real. One of my very best friends is gone and the place she holds in my heart will never be filled. Brittany was one of the coolest people I've ever known, filled with the loudest and most contagious laughter, a huge heart, a beautiful smile and an unbelievable faith in others that not a lot of people have. It was such a blessing having her stand by me in my wedding and I was honored to stand by her in hers. From way too much eye shadow, bangs, boyfriends we THOUGHT were our soul mates, trips to Destin and Cancun, late nights at the Blanton casa with way too much queso, to growing older, nights of reminiscing, phone calls to help eachother keep our chins up in the tough times, and laughing at how cool we thought we were back in the day….and still eating way too much queso….you will forever be missed. Reserve me a spot next to you in Heaven BB, I know I'll see you there again one day. Love you

This is absolutely heartbreaking. While she hasn't gone into detail about what happened, it sounds like an unexpected loss.

We'll definitely be thinking of Tiffany and Brittany's friends and family. Send your kind thoughts to them in the comments!
