Ryan Reynolds and Sandra Bullock have been rumored to be a couple multiple times over the past year, but the duo has insisted that their relationship is strictly platonic and they are nothing more than good friends.

However, the former co-stars have given us another reason to question their 'friendship', when TMZ photographed Reynolds on a vacation with Bullock and her adopted son Louis in Wyoming!  The threesome were spotted on a hike at the Grand Teton National Park. And the cutest part?!  Reynolds carried Bullock's son in a backpack carrier the entire duration of the hike!  The hike is part of a vacation to the nearby Jackson Hole, where Bullock & Reynolds are vacationing with a few other pals.

The duo was spotted together recently, as well, at the premiere for Reynolds' latest movie The Change-Up, where Bullock surprised him on the red carpet in Hollywood! 

The rumors of the two friends starting a relationship began last year, after Bullock divorced from Jesse James and Reynolds divorced from Scarlett Johansson.  Since then, Reynolds has been linked to Charlize Theron, while Bullock has spent most of her time taking care of her new son. 

Do you think Ryan Reynolds & Sandra Bullock are for real this time?!
