Prince William had Kate Middleton in mind during his recent solo engagement.

The Prince of Wales visited the WEST Youth Zone in West London on Thursday. The $15 million facility, which officially opens in April, is named WEST for "Where Everyone Sticks Together" by youngsters who use it.

During the trip, Prince William joined the kids in decorating biscuits. In a video shared by Sky News, one praised the heir apparent's decorating skills, saying he was "impressed." However, Prince William dismissed the compliment and praised his wife instead.

"My wife is the arty one," the royal father of three said.

Prince William also mentioned their three children, saying Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5, "are artier" than him.

The video received mixed responses, with some joking about Middleton's recent Mother's Day photo controversy. Others also asked where the Princess of Wales was since she had not been seen for months, and her first official photo turned out to be manipulated.

"Not very good at Photoshop, though," one commented.

Another added, "KATE MUST BE BUSY EDITING HER PICTURE SOMEWHERE."

"He meant she's more like the photoshopping one," another user opined with a face with tears of joy emoji.

"WHERE IS KATE DOES ANYONE KNOW!!!" a fourth person asked.

"That's all good and stuff !! But where is our Princess???? What has happened to her??" another said.

Prince William complimented his wife amid the resurfaced rumors about his alleged infidelity that made headlines in 2019. Stephen Colbert trolled the future king on Tuesday's episode of "The Late Show."

"As we were talking about this show yesterday, the kingdom has been all fluttered by the seeming disappearance of Kate Middleton. Well now, internet sleuths are guessing that Kate's absence may be related to her husband's and the future king of England, William, having an affair," Colbert said.

"So, I think we all know who the alleged other woman is -- say it with me -- The Marchioness of Cholmondeley ... now, there have been rumors of an affair between William and [Hanbury] since 2019. According to tabloids back then, when Kate supposedly confronted him about it, he laughed it off, saying there was nothing to it. 'Haha,' always a good response when your wife accuses you of cheating."

Prince William had already addressed the infidelity rumors. His lawyers served legal warnings to at least one British publication that published details of the rumor because the report was reportedly "false and highly damaging."
