Anna Nicole Smith

It's not easy being a former Playboy Bunny who married an old man for money and then gave birth to a controversial daughter years later.

Just ask Anna Nicole Smith.

The busty blonde was recently sued by Larry Birkhead, who claims to be the father of her newborn baby. The suit is requesting a judge to order Anna Nicole return her daughter, Dannie Lynn, to California, submit to a paternity test and have mother and child tested for drugs.

We're guessing this isn't the way Smith had planned on taking her honeymoon.

In a statement released by Birkhead's attorney, Debra Opri, Birkhead is asking for legal and physical custody of the little girl, born September 7th.

It reads he is "a first time father and he is responding to allegations made by attorney Howard K. Stern on behalf of Anna Nicole Smith" and "believes beyond any doubt that he is the father."

This goes to show that you've gotta keep detailed track of who you sleep with. At least Nick Carter appears to be heeding that advice these days.

Last week, Smith's lawyer, Howard K. Stern, announced on CNN's Larry King Live that he was the father of the child and that he and Anna Nicole had been in a relationship for some time.

But Birkhead appeared live on with Rita Cosby on MSNBC last night and declared, once again, that he is the father of the little girl. He told Cosby that he is "outraged and angry" and claims that Anna Nicole deliberately fled to the Bahamas to avoid custody and visitation discussions.

This sounds sketchier than a Bobby Brown child support payment. Maybe.

Cosby also asked Birkhead about unsubstantiated claims that Anna Nicole was pregnant once before with a child of Birkhead's but then miscarried, but Birkhead refused to comment.

How does Anna Nicole Smith mourn the sudden death of her 20-year old son? First, she sells the final pictures of him alive.

Then, she gets married. For the third time.

While it's doubtful Smith and her longtime lawyer and confidant, Howard K. Stern, will top Pamela Anderson and Kid Rock in the multiple marriage department, the two still exchanged vows in a commitment ceremony in the Bahamas Thursday.

The ceremony was not formal and is "not legally binding," attorney Michael Scott said.

So, does that mean we can just announce that we're married to Eva Longoria and have it considered basically valid?

"It was low-key, on a boat," a source close to the couple told People magazine. "It was a simple ceremony, exchanging vows."

On Tuesday, Stern said on Larry King Live that he is the father of Smith's baby daughter, Dannielynn Hope, born Sept. 7 â€" just three days before Smith's 20-year-old son, Daniel, died while visiting his mother in the hospital.

"We love each other and it's been going on for a very long time and because of my relationship as her lawyer, we felt it was best to keep everything hidden. And we've done a pretty good job of that," said Stern.

Kind of like how Lindsay Lohan is trying to keep her dumping at the hands of Harry Morton secret.

Dr. Cyril Wecht, a private pathologist hired by the Smith family to investigate Daniel's death, told People Daniel had been killed by cardiac dysrhythmia caused by a lethal combination of methadone, Zoloft and Lexapro.

He also said on Friday that he has now ruled out any natural cause of death based on tissue samples from Daniel that he examined yesterday.
