I didn't really pay close attention to Tatiana when I looked at the pics but I suppose you guys are right that she certainly gained a little, and it seems reasonable to assume it could depression weight from her father's decease.
True, it's not an alarming gain and she looks fine. It's actually nice to see a girl with a little meat on her bones, a nice relief from pictures of celebrity anorexics.

Now if only Andrea would follow Tatiana's example, hey!!!!
