Prince Harry and Meghan become instant Instagram stars

Social media loves the British royal family—especially the young, attractive couple expecting their first baby.

A brand-new official Instagram account for Prince Harry and Meghan, the Duke and Duchess of Sussex, launched Tuesday and rocketed past 1 million followers in less than 6 hours. That set a new Instagram record, according to Guinness World Records.

The account, which is SUSSEXROYAL, reached 1 million followers in 5 hours 45 minutes, breaking the previous record of 11 hours 36 minutes by K-pop star Kang Daniel, Guinness said.

"Welcome to our official Instagram; we look forward to sharing the work that drives us, the causes we support, important announcements, and the opportunity to shine a light on key issues," the couple wrote in the caption to their first post.

As of Wednesday afternoon, Harry and Meghan's IG had almost 3 million followers but only two posts.

Harry and Meghan's baby is due in late April or early May.
