Tom and Katie -- Wedding Conflict

Tom Cruise and Katie Holmes' wedding may be just around the corner, with her dress all ready to go, but the persistent buzz is that Katie's parents are still outraged that the nuptials -- whenever and wherever they happen -- will be conducted by the Church of Scientology, rather than in the Catholic tradition. And there have even been suggestions that the family Holmes is threatening a last-minute boycott of the wedding to try to convince Katie to have a proper Catholic ceremony, even if she does one Scientology-style, too.

Katie was born a Roman Catholic and went to parochial schools growing up in Toledo, Ohio, and so it would only be fitting for her to be married with the usual Catholic rites -- not in a Scientology ceremony, in which the bride is sometimes called a "girl" marrying a "man" and in which one of the solemn "pacts" of marriage is that the couple agree not to go to bed angry. The Holmes family has not commented publicly on the situation, though the TomKat mothers were spotted recently having lunch with their children. Cruise's rep maintains that the couple will be married sometime in the fall.

Britney Spears has targeted her husband Kevin's album release party at the end of this month to make her triumphant return as the svelte, sexy young starlet we once knew -- and sources close to the family tell TMZ that she's enlisted a small army of nannies, trainers, and nutritionists to put her through her paces to make sure she's looking her best.

According to our sources, Brit has hired a nanny for each of her sons, and is constantly in the gym "for hours at a time," working out feverishly to shed all the extra poundage she put on while having two babies in 13 months -- and indulging her penchant for Taco Bell gleefully and often along the way. "She really wants to make a huge splash at Kevin's release party," says our source, "and she totally wants to outshine Kevin and announce to the world that she's back."

The Anna Nicole Smith saga is just getting uglier. The latest twist is that Smith's mother, Virgie Arthur, has told Page Six that she thinks her grandson Daniel -- who tragically died in the hospital room where his mom had just given birth in the Bahamas -- was murdered. Toxicology tests have shown that Daniel died of an overdose of methadone and the antidepressants Zoloft and Lexapro. "Somebody had to give it to him. He had to get it from somewhere," Arthur reportedly said. "I just know Danny didn't kill hisself. He did not overdose hisself . . . Danny wouldn't take drugs to begin with. I don't believe that for a minute. You could not convince me of that." Smith has not yet held a funeral for Daniel, whose body is still lying in a Bahamas funeral home.

Maybe all that do-gooding by the likes of Bono and Angelina Jolie is contagious. Nicole Kidman is the latest celeb to get in on the act-she arrived in Kosovo yesterday as a United Nations goodwill ambassador. The region was devastated by war in 1998-1999 and Kidman plans on visiting the southwestern town of Djakovica, one of the most hardest-hit areas of the conflict. This is Kidman's first tour of duty since being named goodwill ambassador of the U.N. Development Fund for Women in January.

Diamond merchant DeBeers is gearing up for a fight-over the upcoming Leonardo DiCaprio movie "Blood Diamond," out Dec. 15. In the movie, the African diamond industry is portrayed as a conflict-ridden one, but DeBeers claims that the movie distorts the truth, according to the New York Post ... NBC should start watching its wallet. The network's operating profit fell 10 percent in the third quarter, largely because of expensive shows like "Kidnapped" and "Studio 60 on the Sunset Strip" that haven't lived up to expectations.
