Aaron Rodgers and Shailene Woodley Leave Mexican Getaway

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.

We know what fans desperately wanna see -- Shailene's engagement ring, so here's the best we can do. Even zooming in, it's hard to tell if she's wearing one on that left hand.

We do know the ring exists, but up to this point, the only time we've seen it was when Shailene was on the 'Tonight Show' in February, talking to Jimmy Fallon about the engagement.

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.
