Samantha's Summer Couple Pick- Will they sizzle or fizzle?

This couple fizzled once before but now they are at it again, in hopes of making it sizzle. Since their break-up in March, sexy stars Justin Timberlake and Jessica Biel kept in touch, trying to remain on good terms. Well, now the terms are even better and the once 'off' couple is very much back 'on' again. Multiple reports say the couple is trying to reconcile out of the public eye. But this past holiday weekend, the pair spent quite some time together in Toronto, where Biel is on set shooting a new movie. Will they make it last this time? Or will their relationship fizzle out once more? What do you think?
