So, just where did these two end up?
Grand Teton National Park, where, as seen in pics obtained by TMZ, Ryan and Sandra decided to hit the hiking trails. What's more, the longtime buds were joined by the actress's little son Louis, who Ryan graciously carried in a backpack carrier. The three have been vacationing, along with some other friends, in nearby Jackson Hole.
Of course, this all comes less than two weeks after Sandra surprised her Proposal costar at the Hollywood premiere of his latest movie, The Change-Up. Hmmm.
OK, we'll stop. But, seriously, you can't blame us for wanting to see this darling duo take it to the next level...right?
