is britney the emerging jlo?.........

ok, so i may be a bit naive......but why is britney spears all excited to marry a guy who, until 3 months ago had a girlfriend who birthed him one daughter, and who is set to birth him another soon........am i crazy....or is someone this uncommitted to the mother of his children...a bad risk as a first spouse...........or is britney herself assuming that this is just a trainer marriage.....ala jlo.................and does britney actually understand that she could be called upon to supervise/nurture these existing children....and possibly support them.......................so many questions...that luckily i do not have to answer...........i do predict that the only people happy when all is said and done will be the lawyers.......
