New York, New York - The world got a stunning first look at Kristen Stewart as the ill-fated Diana, Princess of Wales for in the upcoming biopic Spencer.

The former Bella Swan has transformed into a princess.

But, not just any princess.

On Thursday, the world was finally treated to a sneak peek of the film.

For some time, there have been doubts that Kristen could successfully pull off such an admired public figure – and rightfully so. The Twilight alum will portray one of the most iconic British royals who, to this day, remains a fascination.

Yet, the dramatic, albeit brief clip should ease everyone's minds, as it seems the 31-year-old has completely transformed herself into the beloved princess.

The one-minute teaser brings together various scenes of the Christmas evening in 1991 while an eerie rendition of Lou Reed's song Perfect Day plays in the background.

Viewers can see the royal family posing for photos and having dinner, as Diana is slowly losing her way and seemingly in despair over her marital woes.

Towards the trailer's end, Princess Di speaks to her confidante, played by Sally Hawkins, who remarks, "They know everything."

"They don't," Stewart chillingly replies.

Spencer will be released on November 5.
