Nissan just seven minutes after the announcement, promoting the Nissan X-Trail seven seater.
Other brands weren't far behind with messages of congratulation on Twitter, including John Lewis, WKD, Innocent and Morrisons.
These on-the-fly responses are , a growing trend where brands ditch long-term planning for spontaneous reaction to the news. In this case, some managed to have more panache than others, with congratulatory messages ranging from the restrained to the positively lewd.
Congratulations to the Duke and Duchess of Cambridge! We've got a fair few buns in the oven too – at our bakeries of course!
— Morrisons (@Morrisons)
Delighted to hear the news from that The Duke & Duchess of Cambridge are expecting a second child - congratulations!
— John Lewis (@johnlewisretail)
KATE MIDDLETON IS PREGNANT. KEEP CALM, EVERYONE. KEEP CALM.

Some brands were decidedly unimaginative.
You’re the most famous in town and there’s a new challenger to the throne

Others tried to imitate Nissan to produce ads or content at speed. That strategy backfired for WKD, which was roundly mocked for misspelling "Middleton" in its tweet.

Clothing and baby brands went for sheer opportunism.
Congrats Wills & Kate! We're all giddy thinking about just how cute the second would look in !

Congrats on number 2! It’s going to be double duty diapers for you.
