HONEY... PACK THE PORN!

Mommy-to-be Britney Spears had a magical time chillin' with ding-dong-daddy-o Kevin Federline at Disneyland Hotel's Sleeping Beauty Suite during the resort's 50th Anniversary bash... until a horrifying moment: she waltzed in with six Disney publicists while Kevin was sunning himself on the balcony -- and discovered an XXX-rated flick blaring full-blast on the VCR! Beet-red with shame, Brit babbled, "Boys will be boys" -- then rushed to hit the Off button! After an uncomfortable moment, feisty Brit recovered and got nervous laughs when she hollered out to hubby: "Honey, you didn't tell me you'd brought along Sleeping Booty!"
