Xtina's Xtremely Xpansive Xtremities

OK, so obviously we know that Christina Aguilera has gigantic non-genuine gazongas. But have they grown recently? Those things are monumental. Perhaps in her baby-rearing down time Xtina is actually a super talented scientist who has devoted herself to discovering space-age polymers (we're not quite sure what those are; we think we heard about them on The Jetsons) that can grow and shrink at their master's will. Sweater feeling a little loose in the boobal area? All Christina has to do is give her nipples a couple of tweaks and her breast flesh (or flesh-like plasticine material, as it were) will expand to fill in the excess material. By the time little Max turns five, Xtina should be able to discover the key to turning off her magical breast expansion and contraction so she doesn't accidentally smother Jordan Bratman during foreplay.
