To be honest, I'm not really sure why Zac and Ash are here because the ALMA awards honor Latino performers... but whatever, I'll take Zac in a suit any time.

Oh and btw, did I mention Zac had met up with Vanessa on her tour. Trusted sources report he was definitely at the Iowa stop.

ETA: someone from VABN comments said they were there because Kenny Ortega was up for an award. This beats any suggestion I have, so we'll go with it. Kenny was honored for directorial achievement for HSM2. We can see Zac and Ashley present the award to him when the ALMAs air September 12th on ABC.

Also, added more pictures
