Billie Lourd is paying tribute to her mom, Carrie Fisher, with a song on the two-year anniversary of her death Thursday, while author/producer Todd Fisher also remembered his sister Carrie and mother, Debbie Reynolds.

“It has been two years since my Momby’s death and I still don’t know what the “right” thing to do on a death anniversary is (I’m sure a lot of you feel the same way about your loved ones),” said Lourd’s statement on Instagram. “So I decided to do something a little vulnerable for me, but something we both loved to do together – sing.”

“This is the piano her father gave her and this was one of her favorite songs,” she continues. “And as the song says, we must ‘“keep on moving’”. I’ve found that what keeps me moving is doing things that make me happy, working hard on the things that I’m passionate about and surrounding myself with people I love and making them smile.”

Lourd concluded her post with an uplifting note to her followers. “I hope this encourages anyone feeling a little low or lost to “keep on moving”. As my Momby once said, “take your broken heart and turn it into art” – whatever that art may be for you.” It was followed by a heart emoji.

Fisher suffered a heart attack during a flight from London to Los Angeles International airport in 2016. She was rushed to a Los Angeles hospital, where she died four days later, on December 27, 2016. The following day, Fisher’s mother, Debbie Reynolds, died following a stroke at the age of 84.

Also acknowledging the day was author/producer Todd Fisher, the brother of Carrie Fisher and son of Debbie Reynolds. “On this day, I do what I do every day, I remember “my girls” and try to help keep their memories alive.  There is not a day that goes by that I do not think of them, we surround ourselves with things that have personal memories connected to them.  They frequently visit me in my dreams.  They send their love as they always did in my life.”
