Oprah Winfrey made a last minute change to her wedding outfit ahead of Prince Harry and Meghan Markle's nuptials as she didn't want her dress to cause a stir on the couple's big day.

The 64-year-old star had a last minute panic on Friday, worrying that her beige dress looked too white, and has thanked the Stella McCartney team for rustling something new up in less than 24 hours.

Sharing a video on Instagram, she said: "I would like to thank the Stella McCartney team for working all night long to get this dress finished because we had dressgate. Wrong colour. Now we got the right color. I think we're going to do okay."

And in the caption, Oprah gushed about the "extraordinary" day.

She wrote on the photo sharing site: "Thank you @stellamccartney ! Realized Friday morning the beige dress I was planning to wear to Royal ceremony would photograph too "white" for a wedding.Her team did this overnite. Hat is vintage @philiptreacy been in my closet since 2005 with new feathers. OMG was this an extraordinary day! #Harry&Meghan #RoyalWedding #Lovedeveryminute (sic)"
