Kate Middleton and Prince William's third child: See what the new prince looks like!

Duchess Kate and Prince William's new baby boy is as cute as a button! The royal couple's new bundle of joy, who arrived late Monday morning, made his public debut on the steps of the Lindo Wing of St. Mary's Hospital.

Kate dazzled in a Jenny Packham dress (no doubt a nod to Princess Diana) and a pair of nude stilettos, while Prince William looked dapper in a navy suit. However, all eyes were on Britain's newest prince ... and rightfully so. He is just too darn adorable! See the close-up photos of the prince for yourself:

While Kensington Palace has yet to announce the name of Kate and William's third child, bookies revealed the top contenders are Arthur, James and Philip. The latter paying tribute to Prince William's grandfather Prince Philip.

Before bringing baby No. 3 home, Prince George and Princess Charlotte visited the hospital to meet their new little brother. Of course, Charlotte stole the show with her adorable hand waving!

Despite being born less than 24 hours ago, the new prince is already making history. Per the Daily Mail, the birth weight of Will and Kate's second son makes him the heaviest royal baby to be born in over 100 years. For more on the newest royal arrival, watch the video above!
