Is It Time For Your Regeneration Dr Song?

Above are on-set pictures of Alex Kingston's River Song in "Doctor Who: Series 6". Now if I'm not correct, these pictures look like she may be going through a regeneration cycle, just like The Doctor. I've also saw a video that shows us Song doing all the actions that The Doctor would do if he was going through a regeneration cycle. Could she be regenerating? We'll just have to wait and see.
Here's the link to the on-set video: http://www.youtube.com/watch?v=imusU1r7F9M
