Sophia Bush's ex-boyfriend killed in Mount Everest avalanche

Actress Sophia Bush's has paid tribute to her ex-boyfriend after he was killed in an avalanche in Nepal on Saturday (25Apr15).

Google executive Dan Fredinburg, who ironically survived an avalanche in the same region while he was dating the former One Tree Hill star last year (Apr14), was one of 17 killed while scaling Mount Everest.

His death has been confirmed by members of the expedition team he was travelling with.

The avalanche was triggered by an earthquake, which had claimed the lives of more than 1,800 people as WENN went to press.

Bush took to social media to share her thoughts about Fredinburg's death. She wrote: "There are no adequate words. Today I find myself attempting to pick up the pieces of my heart that have broken into such tiny shards, I'll likely never find them all. Today I, and so many of my loved ones, lost an incredible friend.

"Dan Fredinburg was one-of-a-kind. Fearless. Funny. A dancing robot who liked to ride dinosaurs and chase the sun and envision a better future for the world. His brain knew how to build it. His heart was constantly evolving to push himself to make it so. He was one of my favorite human beings on Earth. He was one of the great loves of my life. He was one of my truest friends. He was an incredible brother, a brilliant engineer, and a damn good man.

"I'm devastated and simultaneously so deeply grateful to have known and loved him, and to have counted him as one of my tribe. I was so looking forward to our planned download of 'all the things' when he got home. I am crushed that I will never hear that story. I am crushed knowing that there are over 1,000 people in Nepal suffering this exact feeling, knowing that they too will never hear another tale about an adventure lived from someone that they love.

"Disasters like this are often unquantifiable, the enormity is too much to understand. Please remember that each person who is now gone was someone's Dan. Please remember that our time on this Earth is not guaranteed. Please tell those you love that you do. Right now. This very minute. And please send a kiss to the sky for my friend Dan. His energy is so big and so bright, and it's all around us, so put some love toward him today. And then hug your loved ones again."

She ended her Instagram post with the hash tag "goodbyesweetfriend".
