For people who saw the photos last week of a tankini-clad Tina Fey vacationing in Orlando, they were a welcome and rare glimpse of the busy writer-comedian in relaxation mode. For the 42-year-old mom of two, though, they were nothing short of mortifying.

"My nightmare came true and I was photographed in my bathing suit in Florida. Thankfully, I was mostly submerged," the actress told USA Today.

"It was at Disney World. I felt like it had to be another guest," she continued of the unknown shutterbug.

In the pictures, a fit Fey — wearing a modest, navy blue, polkadot tankini top and matching swim shorts — plays around in a pool with adorable daughters Penelope, 19 months, and Alice, 7.

The Bossypants writer, who hosted the Golden Globes in January and recently wrapped up 30 Rock, is now busy promoting her latest movie, Admission, with Paul Rudd.
