What's up with Justin Timberlake and Jessica Biel?

Justin and Jessica were seen riding bikes around Toronto this past Sunday. 



This leads us to question....are they back together?  Does this mean all of the rumors about Justin and Mila Kunis were false?  Justin and Jessica broke up 5 months ago after dating for 4 years.  Lets hope these ex-lovers are rekindling the flame.

(Totally unrelated, but I love this video!)
Remember the good old days.
