Anna Nicole Smith’s longtime companion and lawyer Howard K. Stern took the stand in a Florida courtroom Tuesday, calling the former model “pretty much my whole world.”

“She was my best friend, lover, the mother of my daughter – literally everything to me,” he said on the stand when asked about the nature of his relationship with Smith, Fox News reports.

During H.K.S’ testimony in the battle over where Smith’s body will be buried, he said that Smith, who died on Feb. 8, purchased a double-plot for herself and her deceased son Daniel in the Bahamas.

“If Daniel has to be buried, I want to be buried near him.”

He also said that the pair began an intimate relationship in 2000. “It was not exclusive… It was something we did not disclose to other people. And she had other boyfriends in between.”

Also in the courtroom were Larry Birkhead, who also claims to be the father of Smith’s daughter, Dannielynn, and Anna Nicole’s estranged mother Virgie Arthur, who is fighting to have custody of daughter’s body in order to have her buried in Texas.

Before entering the courtroom, Larry told Access Hollywood that the thought of Dannielynn’s happiness was keeping him going. “I just look at a picture of my daughter and that’s all I really need to see, to keep me strong.”

Meanwhile in a California court, Los Angeles Superior Court Judge Robert Schnider ruled on Tuesday that the Florida coroner must allow Birkhead’s experts to test the DNA samples that were already taken from Smith’s body to determine paternity of Dannielynn.

A hearing on the matter is set for next month.
