I assumed that this was a slap of some nature at Ms. Lopez. I wonder if she got it? I'm guessing that she didn't.

Or she could be deliberately poking fun at herself, or maybe poking fun at those who criticize her singer-cum-actor image. I consider that a much more plausible explanation.

A basic assumption is being made here: That singing and acting are two separate kinds of careers. My opinion is that they're both show business, and there are some performers who are well suited to both. I say, more power to 'em.
