In reply to Tio.

Mariah would likely decline. She and Aretha were REAL friends (unlike the fake relationship they are trying to give to Ariana all of a sudden). Mariah said she learned from the MJ funeral performance that should can't sing at funerals because the sorrow affects her voice. She is such a genuine singer who truly loved Aretha.

But i'm sure Mariah will be in the front or second row at the very least, just like she was there for her friend, Whitney :)
