Bella Thorne mourns Bill Paxton's death

Sometimes it's easy to forget how many television shows and Hollywood projects Bella Thorne has been involved in. She's got so many things under her belt and is taking on even more projects in 2017.

Unfortunately, over the past couple of days, Bella has reminded her fans of something she worked on years ago and she's reminding the world of it for a very sad reason.

Bella's television co-star and on-screen dad, Bill Paxton, sadly passed away at the age of 61. The Shake It Up star was incredibly upset and speechless over his death. She posted an amazing tribute to Bill on Instagram that has forced fans to get their tissues out.

Bella wrote, "Oh my goodness...I don't even know what to say thank you bill for being such a good tv dad to me and spreading love on every set you work on..my thoughts and prayers go out to your family. We love you #billpaxton 💔 #rip."

Bella was super young when she worked with Bill on the HBO series Big Love, but clearly, he had a profound impact on her. She played the role of Tancy "Teeny" Henrickson on the show. While she may have been a kid, Bill was still someone who played her TV dad and she'll never forget him. Just to take a little trip down memory lane, this is a photo of Bella playing her character on Big Love.

Bella not only took to Instagram to express her sadness but also Twitter. She tweeted, "Noooooo #BillPaxton f--k💔 I love you man."

Bill died over the weekend after complications from surgery. He had a heart condition and was getting surgery due to that. Sadly, he passed away during the whole thing. A rep for his family broke the news to the world with a heartbreaking statement.

"A loving husband and father, Bill began his career in Hollywood working on films in the art department and went on to have an illustrious career spanning four decades as a beloved and prolific actor and filmmaker. Bill's passion for the arts was felt by all who knew him, and his warmth and tireless energy were undeniable. We ask to please respect the family's wish for privacy as they mourn the loss of their adored husband and father."

Our thoughts and prayers are with Bill's family, friends and fans.

As for Bella's IRL dad, he passed away in 2007 in a car accident. Today marks his birthday, and she sent out a heartbreaking tweet.

"Happy birthday daddy. I refuse to cry today," she wrote.

Okay, well now we're crying.

All the love Bellz.
