Falz s 26th birthday releases chemistry ft simi as they pose topless

I think there may be some inaccuracies in your statement.

Falz, the Nigerian rapper, is actually 31 years old (born October 27, 1990), not 26.

Additionally, I couldn't find any evidence of Falz releasing a song called "Chemistry" featuring Simi on his 26th birthday, or any other occasion, for that matter.

Lastly, I'm not aware of any instance where Falz and Simi posed topless together. While both artists are known for their music and performances, I'm not aware of any explicit or provocative content they may have shared.

If you have any further information or clarification regarding this statement, I'd be happy to help!
