During a recent trip to Mexico City accompanying Ozzy Osbourne on tour, Sharon Osbourne learned a harsh lesson: never forget your passport when you travel internationally.

Osbourne posted a photo of Ozzy Osbourne aboard their private jet on her Instagram account with the caption, "Ozzy on his way to Mexico and performing in front of 80,000 people and I had to miss the whole thing as I forgot my passport at home in the U.S."

Mrs. O. detailed the ordeal on The Talk (as seen in the player above). "I was on that plane, and we landed in Mexico City at, like, twenty to six in the evening on Friday and I realized I had forgotten my passport," she said. "So the first thing you think of is, 'Oh. If I sit here, I can get somebody to bring me my passport. I'll sit here for five hours. We're in the airport, and then I can go through immigration.' Well, no. I couldn't. Ozzy had a show to get to and all of the guys were going to the show, so he had to leave me."

She continued, "So I'm there with the pilot, and then we were saying, 'Somebody will come with the passport.' They said, 'No you can't. It doesn't work that way. You have to leave the country.' But you can't get on a plane without your passport! This was a private plane, but if you want to go on a commercial airline, you need your passport to get back to America, so the airlines wouldn't take me. So I'm stuck."

Osbourne stated that the local authorities considered putting her in a "holding tank" before eventually deciding to let her fly back home aboard the jet, but at that point the airport had closed for the night, leaving Sharon to sit on the runway until the next day when everything re-opened.

"I sat there from twenty to six until 10:30 the next morning because they kept saying, 'You can leave. You can leave. The airport opens at 6:00, 6:30, so then you can leave.' Well no. I couldn't leave. They still said, 'You can't leave. We've got paperwork to do on you.' 'Okay. Alright,'" said Osbourne. Eventually, the plane was allowed to leave with Osbourne, and she finally returned home to Los Angeles on Saturday afternoon.
