Since then Grimes has Tweeted an apology which reads: “I spoke with Shivon at length finally, which was long overdue. This wasn't her fault, plz don't be angry at her! We respect each other a lot and we're excited to become friends and have the kids grow up together.”
She continued: “Women are so often pitted against each other. Speaking with Shivon, it's very evident she's an amazing human and we both just want what's best for our kids.”
Her statement concludes: “I wish I could show u how cute little Techno is but my priority rn is keeping my babies out of the public eye, Plz respect that at this time”.
