• One-year-old X Æ A-Xii looked happy to be sitting on Musk's lap as he said "hi" to others in the meeting.

Elon Musk's and Grime's son made an appearance in a SpaceX meeting earlier this week, with the smiley baby sitting on his dad's lap.

One-year-old X Æ A-Xii waved his arms and said "hi" to others in the meeting before he was tearfully taken out of the room.

Musk and musician Grimes welcomed their son in early May. The two split in September after three years of dating. Musk told Page Six that the couple "semi-separated" but still loved each other and "are on great terms," Insider previously reported.

The former couple faced scrutiny, and Grimes publicly defends Musk's wealth, political donations, and treatment of employees on social media. Grimes was involved in Musk's incident with the Securities and Exchange Commission over his infamous "funding secured" tweet in August of 2018. They appeared to break up shortly following the incident but later got back together.

Musk has six other children from previous relationships.
