Simple Plan never said what videos they were going to record when they were in LA, only that they were going to record two videos.
We got to know that the first one would be Can't keep my hands off you, it was recorded March 31st and it seems like they did a very good job!

And then we got to know that the second video would be Astronaut, which was recorded yesterday. We don't know much about that song, only that it's called Astronaut.
We'll get to see when the videos come out!
