And it's completely heartbreaking.
Posting on Instagram, she has uploaded two separate posts that makes one very long letter to Tim, recounting all their beautiful moments together, how she is absolutely broken now that he is gone, and how he was a step-father to her son Luka.
It is seriously hard to read.
She also posted a beautiful slideshow of photos that showed their time together, captioned, "The brightest stars burn out the fastest."
While they're incredibly sweet posts, one look in the comments section shows that some fans are really angry with her. Apparently, Tim's sister posted a comment asking Tereza to delete her posts, as they were exes, and hadn't been dating for a while. Tim's sister's comment was then allegedly deleted by Tereza, making fans believe she had only posted her tributes for attention.
Whatever the drama is, Tereza obviously spent a large portion of her life with Tim, and is in her right to mourn his loss.
RIP Tim <3
