Yep, in the grand tradition of grandparents everywhere, Prince Charles is already doting on his new grandson.
At an appearance at the Whitstable Oyster Festival, the proud gramps graciously received a tiny yellow tee emblazoned with the event's name and happily modeled it for the cameras by holding it up to his chest.
The palace even tweeted a pic of the the royal with the gift, writing: "The Prince of Wales holds up a gift for Prince George of Cambridge during a day in Whitstable #BesidetheSeaside."
The souvenir T-shirt was a gift from Whitstable resident Shona Corcoran and her 3-year-old daughter Hannah, according to the Daily Mail.
"It's one of the Whitstable Oyster Festival T-shirts and we just wanted to give something to George," she explained.
And according to Corcoran, Prince Charles is already predicting that the famous royal heir will be a fan of the cute top.
"He said, 'Oh, that's fantastic, thank you. I'm sure he'll like to wear that,'" Corcoran recounted about her encounter with Prince Charles.
If the little prince is anything like his fashionable mom Kate Middleton, we're pretty sure that if he does step out in the itty-bitty tee, it will sell out in a flash!
