And "Womanizer" by Britney Spears was the No. 1 single on this date in 2008. It's a crap song, as is most of her recorded work, but she looked good naked-but-covered (images mildly NSFW, obviously), especially after having the cliched 2.5 children (two she birthed, .5 she married and divorced).
And really ... if you think Mama Spears' oldest daughter got where she is today due to musical talent, you need to have your hearing checked.
