Kate Middleton showed off her teeny baby bump as she attended the Royal Variety Performance last week. She looked stunning in a floor-sweeping lace Diane Von Furstenberg gown, which we're sure Prince William loved.
But, apparently, he's not the only one that noticed...
Jack Whitehall, who went to the same private school as Kate, performed at the bash and onstage joked that Kate was "the one that got away".

And, when the royal couple met the line-up of performers after the show, Prince William couldn't help but make a joke about it, reports People magazine.
Speaking to Jonathan Ross, Jack said: "William came over and he was very funny, he was very nice but very passive aggressive [and said] 'Oh, so you were flirting with my missus? Oh no that was very funny!'"
He jokingly told Jonathan that he was too young for Kate anyway, adding: "She was a lot older than me. She was in sixth form – it was never going to happen, I was in a head brace!"
The couple stepped in for the Queen and watched the show from the theatre's royal box.
And we got a little bit overexcited with Kate got to shake hands with Harry Styles while enjoying a meet and greet with One Direction, who performed at the show.
Harry's thoughts on the encounter? "I said congratulations on the bump. (Though) she didn't look bumpy." Aww, what a gent.
Kate and Wills are next reportedly set to make a dash across the pond for a trip to New York from 7 to 9 December. We can't wait to check out her Stateside style.
In the meantime, this gallery is packed with more Duchess Kate fashion moments. Enjoy!
