Singer 
Beyonce Knowles, former member of the group 
Destiny's Child,
 looks a bit different if we compare older pictures with more recent 
ones.  Her nose before used to look bigger and thicker, now the bridge 
as the tip look more defined suggesting a 
nose job or 
rhinoplasty, this change looks great on her because she looks completely natural and not with an excess of 
plastic surgery.  Also her lips look thinner than before and many of her fans think that she got some 
lip reduction, but we can't forget that both (nose and lips) can be changed to make them look more defined or thinner with make up.
whether or not she got a 
breast augmentation since
 we only have pictures to compare, but her breast size is definitely 
bigger now than it was before, what make us doubt is that she also 
gained weight since those previous pictures and her breasts do look 
natural sometimes, of course if she wears a push up bra her breast are 
going to look more round but in more regular clothes ("regular" for her)
 her breasts looks like natural breasts would look.  We will keep 
looking for new public appearances to see if we can find some changes 
here.
