I know this isn't big news xD But I trough it was kinda weird..
Just look to this video on youtube:
At the end you'll see them giving each other a kiss on the mouth ! It was on a photoshoot (don't really know wich one..).
And its NOT photoshopped! You can see it yourself in the clip.
What do you think about this? I found it kinda weird :s
I know its just a peck, but still.
