Wedding

Weddings were ceremonies in which two people were married.

The Doctor
Over the course of the Doctor's life, they were married more than once. In 1562, the wedding between the Tenth Doctor and Queen Elizabeth I was attended by the Eleventh Doctor, Clara Oswald and the War Doctor. This came about after the Tenth Doctor accidentally proposed to her in a ploy to prove that the Queen was in fact a Zygon. When it turned out that it was instead his horse that was the Zygon, though, he was forced to carry through with the marriage. (TV: The Day of the Doctor)

In 1782, a wedding ceremony was held between the Eighth Doctor and Scarlette. (PROSE: The Adventuress of Henrietta Street)

In Hollywood in 1952, the Eleventh Doctor accidentally found himself engaged to Marilyn Monroe, and ended up having to leave the party with her to get married. Marilyn got his phone number and attempted to call him, but he denied the legitimacy of the chapel where they were apparently married. (TV: A Christmas Carol)

In 2007, the Tenth Doctor told Sally Sparrow that due to time travel he was "rubbish at weddings, especially my own." (TV: Blink)

After Donna stopped travelling with the Doctor, she got married again in spring of 2010, this time to Shaun Temple. The Tenth Doctor secretly attended this wedding.
