Olivia Newton-John and John Travolta attend The Academy Presents "Grease" (1978) 40th Anniversary at Samuel Goldwyn Theater on Aug. 15, 2018 in Beverly Hills, Calif. 

Grease co-stars John Travolta and Olivia Newton-John reunited on Wednesday (Aug. 15) to celebrate the 40th anniversary of the iconic movie musical.

The two stars met up at the Samuel Goldwyn Theater in Beverly Hills, Calif. for the Academy of Motion Picture Arts and Science's special screening and Q&A celebrating the film, in which the two play high school sweethearts Danny Zuko and Sandy Olsson.

Newton-John, wearing a pink shirt, matching sneakers and a white suit for the landmark occasion, was all smiles at the event, while Travolta, who donned a jeans and a black blazer, busted out some dance moves on the carpet.

They were joined by movie's director Randal Kleiser and costars Didi Conn, who played "Beauty School Dropout" Frenchie, and Barry Pearl, who played fellow T-Bird Doody.
