Happy First Birthday, Suri Cruise!

Yes, the youngest-ever Vanity Fair cover star celebrates the big "1″ today.

Crazy to think that it's been a full year since she was birthed by crazy Katie Holmes. It brings a tear to The Hollywood Gossip's eye.

Not since Howard Hughes has a celebrity so successfully combined fame and reclusiveness like Tom and Katie's little Asian baby, Suri Cruise. 

Representatives for TomKat are releasing no plans of birthday preparations.

However, sources say this celebrity baby birthday is likely to be celebrated in Shreveport, La., where Katie is filming her new movie Mad Money with Diane Keaton and Queen Latifah.

It's her first film since she began her relationship with Tom Cruise.

Rumor has it he's already on his way down there, to celebrate the big day and to make sure his wrongfully imprisoned bride is under his command.

"She is already down there, and Tom and Suri will be flying in," says our source, who did not say just how short Katie's leash is.

In a change of PR reps, Holmes, the possible unnamed subject of a new novel, recently retained West Coast powerhouse Ina Treciokas as her spokeswoman.

"It's part of a plan to normalize the PR, to get it back to what it was before Tom freaked out," says another insider.

"They realize the problems all began when Tom hired his Scientology sister Lee Anne [DeVette] to run the show."
