Historically, William has attended the awards show with his wife. The Prince of Wales only resumed royal duties last week, attending his first engagement on Feb. 14, since the Princess of Wales was hospitalized in January and King Charles III announced his cancer diagnosis earlier in the month.

He hosted an investiture ceremony at Windsor Castle, which acknowledged the exceptional achievements of individuals. The ceremony, which normally takes place at Buckingham Palace, was likely at Windsor Castle so that William could remain close to his wife, who is recovering at their home, Adelaide Cottage, royal expert Hilary Fordwich told Fox News Digital.

Sunday's show was hosted by Scottish actor, David Tennant. 

Many of Hollywood's biggest names were in attendance, including the casts of two of 2023's most esteemed films, "Barbie" and "Oppenheimer."

The award show precedes the Academy Awards in Los Angeles.
