When Ryan Gosling took the stage to rehearse the Oscar-nominated Barbie song "I’m Just Ken" on Friday at the Dolby Theatre in Hollywood, the mood turned electric.

In other words: the Kenergy was very high.

"Ryan was in great spirits, and he was a total pro," a source tells PEOPLE of the upbeat rehearsal two days ahead of the Oscars, which airs on ABC at 7 p.m. EST on Sunday, March 10. "He was joking around and having a great time."

Dressed casually in jeans and a T-shirt, Gosling, 43, showed no signs of nerves as he and Mark Ronson, who is nominated for Best Original Song for co-writing the hit Barbie tune, worked on the much-anticipated musical number. "Ryan was relaxed, his spirits were high, and everyone was having fun," says the source.

While details of the performance remain under wraps, an insider says it will involve "many dancers."

Gosling, who earned a Best Supporting Actor nomination for playing Ken in Barbie, opposite Margot Robbie, is just one high-wattage star set to take the stage on Sunday.
