Meghan Trainor has shared the heartbreaking news of the passing of one of her most dedicated fans, a young woman named Jalisa.

The singer paid a touching tribute to Jalisa, who she hailed as “one of her best friends” as she thanked her for following her around the world and pledged to “never forget” her devoted supporter.

She shared an Instagram collage of several photos of herself and Jalisa over the years and wrote: “I am so devastated by the news of my sweet Jalisa’s passing. Since the very beginning of my career I always had a beautiful familiar face at every single show, all over the world, supporting me and making me smile.”

Meghan went on to say that Jalisa was more than a fan and that she helped build a community of friends everywhere she went – a community called Whalebox, because growing up, Trainor had a whale mailbox.

While it is unclear how Jalisa died, the 25-year-old singer ended her touching tribute by urging her fans to look out for one another and shared the National Suicide Prevention Lifeline number: 1-800-273-8255, for people who are struggling.

“We are stronger together. We need to support and look out for each other. Please know that whatever you’re feeling, you are not alone and there are people that can help,”
