Here's why:
* Andre 3000's artistic career is not widely known: While known for his music, he hasn't publicly displayed or discussed a career as a visual artist.
* "Lava Lady" is not a known subject: There's no documented evidence of this term being associated with Andre 3000 or his potential artwork.
It's possible Andre 3000 creates art privately or has work that hasn't been publicly shown. However, without concrete evidence, it's impossible to say where you might find such paintings.
