Prince George crawls, has a voice that could "match any lion's roar," according to his dad, and sells out any stroller, romper or shoes he's spotted in.

What's not to love?

Nothing according to one young cougar who wore her heart on her sleeve, or her onesie, on Wednesday in New Zealand to grab the attention of Prince George's parents, Prince William and Duchess Kate.

Dressed to kill in a tutu and waving a Union Jack flag, 11-month-old RubyCate Blitz professed her love for the nearly nine-month-old prince with a top that read, "Marry Me George."

RubyCate got a lift from her father, Rob Blitz, in order to stand heads and shoulders above the crowds of New Zealanders who came out to welcome the royal family at a stop they made in Wellington on their multi-week tour through New Zealand and Australia.

It all worked for RubyCate who managed to catch the eye of Prince William, 31, who asked her name and told her parents, Rob and Marqueney Blitz, that she is "absolutely beautiful."

Photos captured Prince William with his mouth agape as he looked at the girl proposing to his first child before calling Kate, 32, over to meet her as well.

"My daughter's going to marry your son," Marqueney Blitz told Duchess Kate, according to New Zealand's The Dominion Post.

"That was so exciting," Blitz told the newspaper after, adding she planned to make a t-shirt for RubyCate for every future Royal visit.

"It's a done deal," she said.

While Prince George was not on hand to see RubyCate's proposal, the young royal has been the star of his family's first official trip overseas since his birth in London last July.

George was greeted in New Zealand with a playdate arranged just for him at the Government House in New Zealand, where he was described as "very intrepid" by one parent attendee and as the baby who "owned the place" by another.

When William, Kate and George arrived in Sydney later Wednesday, Prince George was introduced to local dignitaries while being held alternatively by his mom and dad.

Later that day, Prince George - dressed in a sailboat-embroidered romper - was gifted a giant stuffed wombat by Australia's Governor-General. George greeted the stuffed animal with a smile, as did his father, William, who was nicknamed 'wombat' by his mother, Princess Diana.

The hype surrounding Prince George's adorableness even led to rumors that a sibling for him was on the way after Prince William told a woman who made a gift for Prince George that she might need to make another one.

Those rumors were quelled when Duchess Kate was spotted sipping wine and doing adventurous sightseeing like a whitewater jet boat ride.

For young want-to-be princesses like RubyCate, however, Prince George may be the only prince they need.
