Rachel Bilson and Hayden Christensen - Back Together

According to x17, Hayden Christensen and Rachel Bilson have reunited.

The pair ended their year-long engagement in August, but have reportedly gotten back together as paparazzi have snapped Christensen leaving Bilson's Los Feliz, Calif. house several times in recent days.

While not confirmed by either's reps as yet, the reason most often cited for the initial break-up was… logistics. See, Christensen lives in his native Canada, in Uxbridge, Ontario (he was born in Vancouver), while she remains a full-fledged California girl.

No word yet on how they plan to deal with the often complicated issues that long-distance relationships raise this time 'round, but since he's slated to begin production on "The Cold," which takes place in the woods during a snowstorm, we're guessing that he won't be in Los Angeles long. And, that's probably just as well because, in addition to writing her monthly fashion/style column for "IN STYLE" magazine and her Tre Semme ads flaunting her gorgeous hairstyles, Bilson will be filming "BFF & Baby" opposite Kate Bosworth and Justin Kirk in a few weeks so she'll be too busy to miss him -- much.

Would you like to see Hayden and Rachel reunited and maybe even walking down the aisle? Or, is the old "out of sight, out of mind" adage going to come in to play here?
