Princess Kate burst out laughing as Bradley Walsh made a joke at her expense when opening the Royal Variety Performance.
The comedian joked about being snubbed for an MBE and an OBE at the star-studded show in front of the Prince and Princess of Wales.
The show was recorded on November 30, just two days after Omid Scobie released his controversial book, Endgame. However, it was only aired on TV on Sunday night.
Addressing Prince William, Walsh said: "I have worked for your great nan, your nan, your granddad, your dad, and now I'm working for your Sir and Madam.

"And I must say - ask me if I've got an MBE. Nah, ain't got one.
"Ask me if I've got an OBE - nah, ain't got one of them. Ask me if I've got a CBE - no!"
The comedian went on to say "they've probably run out" of those honours because "they give them all to people who row boats".
Walsh, 63, added that he "entertained troops in the Falklands", while others got commended for their "Victoria sponge cakes".

The comedian also told an anecdote of meeting his two-year-old grandson, who he "promised" that he would ask the Prince of Wales for a knighthood.
This was so the little boy could present his grandfather's title in nursery during a "show-and-tell" session.
At the beginning of the show, the 63-year-old greeted their "royal highnesses", with the camera switching to William and Kate as they laughed.
Walsh pretended to stumble over the word "highnesses" several times.

He said: "It doesn't sound right, your royal highnessesses? There's too many 'ssessess', innit?
"Your royal highness... your royal highnessesses?
"It should be like cactus, cactussess, cacti. Your royal highness, highnessess and highni. That's it. I've got it. Your royal highni."
Meanwhile, the Prince and Princess of Wales were filmed laughing at the slightly awkward joke.
