Sports Illustrated Swimsuit Issue cover girl Kate Upton is giving dads a new reason to take their kids to the park. While posing for the cover of GQ's July issue, the supermodel found herself on a ride at the Santa Monica Pier — topless.

She explains: ""We were on the ride where the seat spins while the actual ride is spinning, and I'm wearing a one-piece. And all of a sudden the whole entire top falls off! I'm holding myself, laughing, turning bright red, but a lot of people are watching, so they kicked us out of the Santa Monica Pier — it was so embarrassing.""

And to think, embarrassing for us is holding up the line at the grocery store when we accidentally forget an item.
