Even celebrities like Chrissy Teigen and John Legend aren't immune to pesky wedding day stressors.

In the spring issue of Martha Stewart Weddings (on newsstands now), the Sports Illustrated model said that bad weather in the States caused problems for guests who were traveling to Lake Como, Italy for the couple's September 2013 wedding.

Storms in Ohio delayed Legend's family members' flights, so the bride and groom had to push the wedding back a few hours.

How did the other guests pass the time?

"They had cocktails for four hours!" Teigen said.

Despite the hiccup, the couple's wedding day turned out to be a beautiful affair. Legend even performed his song "All of Me," which he wrote about Teigen. Footage from the wedding appeared in the music video for the song, which you can watch here.
