M has a better body than all of the other girls mentioned here. everyone says it. people who actually saw her up close in her underwear on stage.
and she looks beautiful, still. she just needs to fire those makeup artists. she looks better when she does little bits of makeup herself
anyway, i think actors age more horribly than singers. gaga's already filling herself with botox and stretching her skin with those tapes so that won't be a good outlook.
