In March, Jonas and Lovato copped to dating one another after months of speculation. Weeks later the pair would open up for the first time about taking their “Camp Rock” relationship offscreen.

As summer approached, the pair began to promote their joint ventures, “Camp Rock 2,” and their summer tour together. However, by May they had split. Still, the youthful twosome pledged that touring together wouldn’t be awkward . Eventually, Lovato left the tour to seek treatment for personal reasons, and well, Jonas hasn’t been shy about his affections for Ashley Greene. We can’t help but hope he and Demi can let bygones be bygones.

Cox and Arquette shocked the world when they split in October after 11 years of marriage. Things quickly got weird when Arquette appeared on Howard Stern’s radio show and dished about the split and his emotional state in a post-Cox world. The bottom line is we expect them to have to reunite once “Scream 4″ hits theaters in 2011. We hope things end better for Gale and Dewey.

If a reality-TV starlet and a pro football star can’t make it, then who can? After battling engagement and pregnancy rumors, Kardashian and Bush called it quits in March after dating for three years. Kim seems to be recovering just fine in the love department, with speculation swirling that she’s dated Halle Berry’s ex Gabriel Aubry and Kanye West . Not too shabby, Miss Kardashian.
