Is Jennifer Lopez Hooking Up With Ex Husband Marc Anthony?

With a reported romance between 24-year-old backup dancer Casper Smart and the Britney-Spears-circa-2001 shimmering nude outfit and side ponytail she rocked on Sunday's American Music Awards, is Jennifer Lopez channeling her inner teenager these days?

Sure seems so: Us Weekly reports that Lopez, 42, recently hooked up with ex-husband Marc Anthony while filming their talent competition "Q' Viva! The Chosen" in Puerto Rico in early November. Messy endings are nothing new in relationships -- Lopez and Anthony split in July 2011 after seven years of marriage -- but what the source tells Us Weekly about the former lovers' late-night hotel room rekindling sounds suspiciously high school: "They may sleep together, but they're over."
