Slash announced the passing of his stepdaughter, Lucy Bleu-Knight, 25, on Monday morning (July 22). In a post, the Guns N’ Roses guitarist and solo star posted a tribute to the young woman he called an “incredibly talented artist, a passionate dreamer, and a charming, lovable, sweet soul.”

The post noted that Bleu-Knight, born on Dec. 6, 1998, was the “beloved daughter of Meegan Hodges and Mark Knight, stepdaughter of Samantha Somers Knight and Slash, sister of Scarlet Knight, stepsister of London and Cash Hudson,” and that she died in Los Angeles on July 19; Slash’s birth name is Saul Hudson and Meegan Hodges is the guitarist’s longtime girlfriend.

At press time no information about Bleu-Knight’s cause of death was available and the family asked for privacy during this time, adding a request that “social media speculation be kept to a minimum as they grieve and process this devastating loss.”

On Sunday morning (July 21), Slash also announced the cancellation of four dates on his S.E.R.P.E.N.T. tour, announcing that “due to unforeseen circumstances, the S.E.R.P.E.N.T. tour regrettably has to cancel the below performances.” A spokesperson for Slash had not returned Billboard‘s request for comment on the cause of the show cancellations.
