Everybody loves Mickey Mouse, and even some stars can be a little obsessed with all things Disney too! Tonight, ET is with such celebrities as Teri Hatcher, Jennifer Lopez and David Beckham as they share their Disney fantasies!

CLICK HERE for a fun gallery of stars at Disneyland and Disney World!

ET's Kevin Frazier was with Teri when they visited Disneyland and toured the Disneyland Dream Suite, a secret 2,200-square foot, two-bedroom suite that lucky, randomly selected winners can stay in for a night as part of Disney's "The Year of a Million Dreams."

"It makes you feel like a little kid, it is so exciting," Teri exclaims, adding, "This is a money-can't-buy experience."

ET got a front-row seat as Mariska Hargitay rode the new Toy Story Mania attraction that just opened at Disneyland, and we joined "Dancing with the Stars" partners Cristian de la Fuente and Cheryl Burke as well as other "DWTS" faves at the Main Street Christmas Day Parade!

And ET was behind the scenes as famed photographer Annie Leibovitz captured the Disney Dream Portrait Series, featuring major stars dressed as some of Disney's most beloved characters, including Jennifer Lopez (who says she wished she was a Disney princess when she was a little girl) and hubby Marc Anthony as Jasmine and Aladdin; Whoopi Goldberg as Genie; Gisele Bundchen and Mikhail Baryshnikov as Wendy and Peter Pan; Tina Fey as Tinkerbell; Jessica Biel as Pocahontas; Rachel Weisz (who remembers her first trip to Disneyland) as Snow White; and David Beckham (who says his kids love Disney) as the Prince from 'Sleeping Beauty.'
