First of all, No I don't think she looks like she has gained weight, so don't go there.
I just have noticed that her wardrobe has been very different lately, like big bulky "men's like" robes. Looser clothes and always black. Also, she has been carrying big bags. Also, they have been putting her behind big flower fixtures.
I definately am not trying to start a rumor just was wondering if anyone else noticed anything?
