The close buds have been fighting rumors that the two are friends with benefits since starring in 2009's The Proposal. The actors' chemistry both onscreen and offscreen chemistry is palpable, but Sandra has protested that "is not my lovah... I don't get his loving after dark.'

Now TMZ has a photo of the three playing family while hiking in the Wyoming wilderness.

A source tells People that the twosome are like 'brother and sister" -- "they love each other, but it is just a very close, wonderful friendship." But aren't the best partners supposed to be friends first?

The two have recently come off rocky relationships, with Bullock ending her marriage to the cretinous Jesse James and Reynolds' divorcing his wife of two years, Scarlett Johannson.
