Seriously -- we didn't think we could possibly love Kate Middleton any more than we already did -- and then this photo of her planting a tree with children comes out. Now our hearts explode a bit more.

On Thursday, the Duke and Duchess of Cambridge visited the National Arboretum, the site of a bushfire in 2003. During the step, Kate visited with local children, planted an oak Tree and did it all while looking absolutely fabulous.

Today is the last day of the the Royals' three-week tour of Australia and New Zealand. Currently, the Brits are making several stops through the Australian capital of Canberra. Say it ain't so!

For the tree-planting, the 32-year-old showed off her green thumb outwardly with an emerald green Catherine Walker coat dress.

The Duke and Duchess had all eyes on them when they later made a stop at the Parliament House, where Prince William made a speech reflecting on their trip with their son Prince George.

"Reluctantly, Catherine, George and I leave Australia tomorrow," William said. "Thank you for the warmth and generosity that has been shown to us during our visit. We go away with wonderful memories, and George goes away with his cuddly wombat, which he has taken to chewing so lovingly. We greatly look forward to coming back. And when we do return, it will be to marvel again at all that Australia is, and will yet become."

Oh my gosh -- we love Prince William's British wit! But what we will miss most about the lack of daily photos of the young family -- that adorable Prince George!
