Team USA, you have no idea how many people are rooting for you at home.
While posing arm-and-arm, the Hollywood couple showed who they will be rooting for in the next two weeks.
"Go team USA!!! We got your back!" Ashton shared on Instagram while showing off their light-up ensembles. "Ty for the blazers @ralphlauren #liketolight."
And if you were extra curious to find out what sport they would compete in, we have your answer. "Arm chair Olympians," the proud dad joked while smiling for the camera.
As you likely could have guessed, Ashton and Mila weren't the only famous faces watching the world unite during tonight's opening ceremony.
Andy Cohen, Pink, Holly Robinson Peete and Michelle Collins were just some of the stars watching the celebration from home. Even Ryan Seacrest was able to tune in before he reports for duty and provides late-night coverage for NBC.
"My #OpeningCeremony highlights so far," he wrote on Twitter. "Giant pop tart pillows, Gisele's world record walk in heels, refugee team, @MLauer's white pants."
And we can't forget about Michael Phelps and all the talented athletes representing the states.
