Here it is ... Aaron Rodgers and Shailene Woodley in the same place at the same time, for the first time since they got engaged -- which might be what they were celebrating down in Mexico.
The happy couple was on the tarmac Monday in Costa Careyes ... moments before boarding a private jet. The Green Bay Packers QB and "Big Little Lies" star were with a group of friends getting ready for takeoff. It's unclear if they're continuing the vacay somewhere else or heading home.
Still, looks like they enjoyed the warmer weather down south after they were together earlier this month in freezing Montreal ... where Shailene was shooting the cop thriller "Misanthrope" and sending Aaron out to walk her dog.
As we reported ... Aaron announced his engagement to Shailene back in February after winning the NFL's MVP award for the 2020 season, and he's since gushed about their relationship and set his sights on having a kid with her.
But, until then ... travel the world while ya can!!!
