"To celebrate the birth of the newest addition to the British monarchy, the DQ brand has temporarily nicknamed its popular Mini Royal Blizzard Treat the 'Royal Baby Blizzard Treat,' and is giving fans a sweet way to celebrate with a returning favorite," Dairy Queen announced in a press release.

The nickname came as a celebration for the royal news and, according to a spokeswoman, will run through the month of May. "There is no signage in-store or online but employees have been informed of the temporary change," DQ told ABC News.

The baby, who was born Monday at 5:26 a.m. local time and weighed 7 lbs. 3 oz, has yet to have his name announced.

We'll just have to wait and see if DQ churns something out when the royal family makes a name official.
