Length of relationship: 1-2 months
Latest rumors: The recently divorced singer and the backup dancer flirted for awhile and began openly dating in November, even going on vacation together with her two kids.
Chances their relationship will hit the one-year milestone: Mediocre. While J. Lo is a serial monogamist, is quite marriage-addicted (she's just finished with #3), and has dated a backup dancer before (Hubby #2, Cris Judd), I'm gonna guess that Casper is in it for the fame and J. Lo is just wildin' out following her break from that control freak Marc Anthony.
