Katy Perry's chest continues to make people uncomfortable. Her décolletage was electronically downsized in promos for an upcoming VH1 special according to Us.

The pop starlet's latest mammary snafu comes two months after 'Sesame Street' pulled an excessively chesty duet on her hit 'Hot N Cold' with Elmo. (Thus ensuring a YouTube sensation.)

To publicize Dec. 5's "Divas Salute the Troops" special, Perry posed for VH1 as a World War II-era pinup girl. But when her reps saw the photos, the magazine reports, they were alarmed at how voluptuous Perry appeared.

"It's true," a snitch tells Us. "The ads are being redone!"
