Following his Oscar win, Argo star Ben Affleck shaved his beard.

The Argo director and star, who captured hearts during his Oscars acceptance speech Sunday night for Best Motion Picture, decided to part ways with his beard, E! News reported.

According to reports, Affleck had kept his beard grown as he awaited for the awards ceremony to take place, believing it was his good luck charm.

"He did it to mark the end of a chapter. It had that ceremonial quality to it," a source said.

It was while celebrating the film's win during an Oscar after-party Sunday night at Craig's restaurant in West Hollywood, that Affleck made the bold decision to shave off his facial hair.

Affleck reportedly shaved because "his family was tired of the beard."

The proud star who was not nominated for Best Director, gave an emotional acceptance that included admiration for his wife Jennifer Garner for "working on their marriage for 10 Christmases" and lessons he's learned in Hollywood since getting into the industry at a young age.

"I never thought that I would be back here," he said, "and I am. Because of so many of you who are here tonight. Because of this academy. Because of so many wonderful people who extended themselves to me when they had nothing to benefit from it."

Argo took home the award for Best Picture, becoming only the 7th film not to take the Best Director award, which went to Ang Lee for Life of Pi.

The film is based on the 1980 joint CIA-Canadian secret operation to rescue six fugitive American diplomatic personnel out of revolutionary Iran to bring them back to the United States without being caught.

"You have to work harder than you think you possibly can. It doesn't matter how you get knocked down in life because that's going to happen. All that matters is you have to get up," Affleck said.
