I dunno about ALL the plastic surgery ... she's had a nose job, and recently it looks like she's definitely had breast implants done. Thats about all I can see.
Who wants a woman who looks like Michael Jackson? That would completely freak me out. Granted, LaToya is basically Michael in drag, but Janet still resembles her alleged-pedophile brother. Enough to make me slightly uncomfortable. Meh. I say Justin can do better than Janet. (Ugh. I can't actually believe I just said that, too...)
Bottom line: If one is aesthetically comparing Janet and Britney, its hard to go wrong either way. Justin is leading a charmed life.
Michelle's great....she sings great and she plays guitar...perfect. Also, she seems extremely nice and all that...altho' most rock chicks seem that way. (exception: courtney love)
