The Ticket talked about this gal the other day, and I've seen at least two other people write about her since then. She is Camille Cortinas.
Her current claim to fame? She's the voice behind the kidnapping-of-the-mind song, "Lucky Day", which promotes the Texas Lottery.
You can find a quick loading link to the song here. But I promise you, if you listen to it, it will be struck in your brain pan for the rest of the day. Or longer.
