You thought the best place to ask this would be in the engineering section?
Anyways, since you have asked in the engineering section I assume you are after a engineering answer:
Weight is the measure of the force of gravity (9.81 m/s^2 in most cases) acting on an object, so it can be calculated using Newtons second law of motion F=ma in your example Weight = m(9.81).
If you want to go into further detail and calculate the force of gravity much more accurately then use the formula:
Fg = G (m1*m2)/(d^2)
where G= gravitational constant (6.67*10^-11 Nm^2/kg^2)
m1 and m2 = the masses object 1 and object 2 respectively
d=the distance (in meters) between the two objects
So the final formula for Christina Aguilera's weight would be the following:
Weight = mass(G (m1*m2)/(d^2))
This should give you a very accurate weight. Just to let you know, I know you wernt after this long mathematical explination and it was probably an accident that you posted this in the engineering section, but I am bored....
