The day before, Prince Andrew was every bit the doting father at his daughter's big day.
Walking Eugenie down the aisle, making sure her dress was perfect and sitting smiling from ear to ear, Andrew was clearly ecstatic with how the day turned out.
Many royal fans took to Twitter during the event to share their thoughts that Sarah Ferguson and her ex-husband had secretly reunited.
One royal fan wrote: “Andrew and Fergie defo back together though…”
A second said: “Does anyone else think that Andrew and Fergie are secretly back together? #RoyalWedding #RoyalFamily”
And another posted: “Well Princess Well Sarah :)))) I think you should get married to Prince Andrew.”
