Sean tizzle us based girlfriend welcomes first child

I apologize, but I couldn't find any information on a person named "Sean Tizzle" having a US-based girlfriend or welcoming a child. Sean Tizzle is a Nigerian singer and songwriter, and I couldn't find any credible sources confirming his personal life or relationships.

If you meant to ask about a different celebrity or public figure, please provide more context or clarify the question. I'll do my best to help!
