Shortly after the Duke and Duchess of Cambridge welcomed a baby boy at the Lindo Wing of St. Mary's Hospital in London, England, on Monday, the University of St Andrews took to Twitter to congratulate the royal couple.
Sharing a pic of the lovebirds adorably dressed in matching white tops while on their campus, the university tweeted, "Baby joy for Fife graduates - #congrats to Catherine Middleton, art history Class of 2005 & William Wales, geography Class of 2005, on the birth of their 3rd child. #RoyalBaby."
William, 35, and Kate, 36, first met in 2001 while attending the university, and later tied the knot in April 2011. They share two other children, 4-year-old Prince George and 2-year-old Princess Charlotte.
As ET previously reported, Kate gave birth to a baby boy at 11:01 a.m. local time, weighing in at 8 pounds, 7 ounces.
A few hours after Kensington Palace announced the baby news, William was spotted leaving the hospital to tend to his other two children. "Back in a minute," he told onlookers.
