Grimes, a Canadian singer and former lover of Elon Musk, startled fans by canceling her next musical engagement, claiming unclear family reasons.
The artist, 37, whose actual name is Claire Boucher, has three children with Musk: four-year-old boy X Æ A-12, three-year-old Exa, and two-year-old Techno.
She came to Musk's social media platform X to make the poignant news and apologize to her admirers.
'I'm really sad and regretful to tell that I had to cancel my pride performance in order to cope with family concerns,' she added.
Grimes extended her love and appreciation to her fans, vowing to'make this up' to them'very soon,' before signing off with a message of'so much love always.'
The declaration follows a highly publicized and lengthy court struggle between Grimes and Elon Musk over co-parenting decisions for their eldest son, X.
