It was a hit on VH1 and routinely made the VH1 top 20 back around I'd guess 2009-2011 but I never heard it on the radio.

Artist was a female and she had had a latin name. No band name; the act was simply her name. Like Ariana Grande (but it wasn't her).

Music video was filmed at a swimming pool in Palm Springs, CA and she sings and dances by the pool with people of all ages, including silly old people. It looked like a very cheap video, filmed in one day.

That's it. Well done. I've googled it many times and found nothing. What was your secret?

And in hindsight that's not Palm Springs; looks more like Burbank.

My secret was looking at VH1 top-20 lists (oh, the horror) between 2009 and 2011. Yes, I don't have a life. Took me about an hour. You're welcome.
