Kristin Cavallari pays tribute to her brother on second anniversary of his death

Kristin Cavallari remembered her brother Michael Sunday on Instagram on the second anniversary of his death.

"This past week has been hard- it's the 2nd anniversary of losing my brother," "The Hills" and "Laguna Beach" alum wrote alongside a black and white photo of her and her brother as children.

"Even though the date we go with is the 27th, for me it will always be the Saturday after thanksgiving (we will never truly know the exact date even though we have a pretty good idea). We lost him completely unexpectedly and it's been a rough road for me and my family," she continued.

"I've had some incredible signs from him though- which give me a lot of peace- including one today. We love and miss you everyday Mikey."

Michael was found dead at age 30 in December 2015 outside Salt Lake City after being reported missing.

Cavallari also paid tribute to her brother on the first anniversary on his death writing, "Love and miss you."
