Beyonce is a triple threat; she sings, she acts and she dances. What she doesn't do a lot of is plastic surgery. Beyonce has had a nose job, and breast implants. Compared to other celebrities of her stature, this is a relative small number of procedures. Maybe this super star, is also super confident.
Beyonce has had a nose job. This before and after picture clearly shows the difference between Beyone, early in her career, and today. Her nose is now thinner and the tip has a more defined point.
It also appears that Beyonce has had breast implants. Though not a huge change, this before and after picture shows the clear difference.
