Grease [1] turns the big 4-0 this year, and what better way to celebrate the iconic musical's anniversary than with a sweet reunion of its stars? Olivia Newton John and John Travolta [2] hit the red carpet at The Academy Presents Grease 40th Anniversary event at LA's Samuel Goldwyn Theatre on Wednesday, where they immediately embraced and busted out a few of their dance moves [3]. They also snapped a few selfies with fellow guests and chatted up Mario Lopez, who arrived on a pair of crutches.
This definitely isn't the first time they've shared an adorable reunion this year, however — the pair actually linked up back in January at the G'Day Black Tie Gala [4], where they enjoyed a few laughs (and gave us a heavy dose of nostalgia). Although we're not sure if they discussed THAT chilling Grease theory [5], it certainly looks like they had a blast. Take a look at all the photos of their outing ahead!
