Michael and Carole Middleton arrive to meet the newborn Prince!

First-time grandparents Michael and Carole Middleton visit the St. Mary's Hospital to meet the newborn Prince.

Brand new grandparents Michael and Carole Middleton have arrived at St. Mary's Hospital to meet their first grandchild.Kate Middleton's proud mother and father arrived at the Lindo Wing shortly after 3 p.m. London time, on Tuesday afternoon, less than 24 hours after their daughter welcomed a little boy.

The delighted couple, who arrived by taxi, smiled excitedly as they made their way inside to see Kate and her husband Prince William, and of course, enjoy those precious first cuddles with their newborn grandson.

Upon leaving the hospital, the Middletons described the baby as "absolutely beautiful," with Carole adding that the new parents were "doing fabulously."

"They're both doing really well," she said of William and Kate. "We are so thrilled."

When asked for a clue on the baby's name, she said with a smile, "Absolutely not!"

Carole and Michael are the very first guests to visit Kate and William in hospital, and meet the tiny arrival. Once they stepped into the private suite where the little Prince was delivered at 4:24 p.m. on Monday afternoon, there would no doubt have been a few tears as the family celebrated this very special moment behind closed doors.

While the arrival of the royal baby is an important historic event, it is of course a tremendous occasion for both the royal family and the Middletons.

The little Prince is the first grandchild for both Michael and Carole, and William's father Prince Charles; a cause for great celebration in both households.

Michael and Carole would have been among the first to receive that joyful phone call from proud new father William on Monday afternoon. While Kate enjoys a famously close relationship with both her parents, William also feels very much at home with the Middleton family and would have taken great delight in sharing the news with them.

Kate's parents arrived in London from their home in Bucklebury, where it is thought the Duchess will spend the first few weeks of motherhood with her baby son.

Carole, in particular, is expected to be instrumental in the little Prince's childhood, and, as such, will play a pivotal role in shaping the future of the monarchy. In the months before the birth, she was pictured shopping with her daughter for the new arrival, and will no doubt been on hand to offer her advice and experience to the couple over the coming months.
