Billie Lourd shares sweet message on 4th anniversary of mom Carrie Fisher's death

Billie Lourd is sending "love and strength" to fans on the 4th anniversary of her mom Carrie Fisher's death.

On Sunday, Lourd shared a throwback photo of her with her mother on Instagram.

"Sending my love and strength to everyone out there that's missing a loved one they've lost," Lourd wrote. "Especially those of you who have lost someone during this crazy year. You're not alone. ❤️"

Fisher died Dec. 27, 2016, after suffering a heart attack at age 60. In October, for what would've been the Star Wars actress's 64th birthday, Lourd posted a photo of Fisher when she was pregnant with her.

On Mother's Day, Lourd similarly sent well wishes to people who've also lost loved ones.

"Sending my love to anyone who has lost a mother and anyone who might just be having a complicated Mother's Day this year," she wrote. "This is my 4th Mother's Day without my Momby and days like today are never easy, but I've found that doing things that make me feel more connected to her make it a little easier — watching her favorite movies, listening to music we listened to together, looking through old pictures and my personal favorite — eating + drinking things she loved."

The Booksmart actress welcomed her first child in September and gave her son a middle name honoring her mom.

"👑💙👑Introducing: 💙👑💙Kingston Fisher Lourd Rydell💙👑💙" the new mother wrote in the caption, sharing a photo of her son.
