Elon Musk’s son X Æ A-XII is growing up right in front of our eyes!
Over the weekend on Twitter, the CEO of SpaceX and Tesla, Inc. shared a rare photo of his 9-month-old child, whom he shares with Grimes.
“The Second Last Kingdom,” he captioned the sweet pic, in which X Æ A-XII tugs on his father’s shirt.
Not to be outdone, the musician, born Claire Boucher, also shared an adorable pic of her child on Instagram.
“Tell me of the waters of your homeworld,” the singer captioned a photo taken by Symone Holliday.
Back in May, Musk confirmed X Æ A-XII’s birth, writing on Twitter, “Mom & baby all good.”

That month, Musk “liked” a tweet that appears to confirm that the pronunciation of his son’s name is “X Ash Archangel.”
Though the pair initially named their baby “X Æ A-12 Musk,” they were forced to change it to “X AE A-XII” because California law prohibits special characters and numbers in names.
According to US Weekly on Monday, Musk and Grimes are “still coparenting” their bundle of joy.
“Grimes was still living with Elon before and after she gave birth,” a source told the outlet. “He is still involved in the baby’s life and his whole family is as well.”
The insider adds that Musk’s mom, Maye Musk, is “especially hands-on and loves helping out.”
X is Grimes’ first child, and Musk’s seventh. The engineer shares six sons with first wife Justine Wilson, a Canadian author. Musk and Wilson’s eldest, Nevada Alexander, tragically died of sudden infant death syndrome at the age of 10 weeks.
