AceShowbiz - Kim Cattrall made use of her social media accounts to pay tribute to her late brother Christopher. On what would have been his 59th birthday, the Golden Globe winner shared a throwback picture of her and Christopher while advocating for suicide prevention.

Alongside the sweet picture, the "Sex and the City" alum wrote on the blue bird app on Sunday, January 2, "Today would have been my baby brother Chris's 59th b'day. Happy Birthday, sweet 'Topher.' " The Samantha Jones depicter on the hit show added, "We miss you today and everyday. RIPx."

The "How I Met Your Father" star also hoped that no one would end up like her brother. Concluding the message, Kim included a hashtag for suicide prevention.

Christopher died from suicide in February 2018. At the time, she enlisted fans' help in finding her brother five days after he went missing in Lacombe, Alberta, in Canada back in 2018. "This is not like Chris," Kim said. She also noted that her brother's home was left unlocked and he left his keys, phone, wallet as well as his seven dogs behind.

Hours later, Kim announced Chris' passing on Twitter. "It is with great sadness that myself and my family announce the unexpected passing of our son and brother, Chris Cattrall," she wrote at the time.

Opening about her brother's devastating death, Kim said in a 2019 interview that the loss has taught her to appreciate her relationships. "I think recently the thing that has taught me the most is loss," she shared. "I've lost two family members and I think what it teaches me, I'm not there yet, but to really enjoy what you do, your family, your friends, to really appreciate … when I say goodbye to somebody I'm not going to see for awhile," she added. Kim lost her father Dennis Cattrall to Alzheimer's disease in 2012.

"The thought is now I might not see them again, or for a couple months, but I want to keep those connections. I feel I value them much more, they take up more of how I want to spend my time because I realize how precious it is," she explained.
