Anna Nicole ex snaps up lingerie for Dannielynn

They're not traditional family heirlooms, but Larry Birkhead's is not a traditional family.

Anna Nicole Smith's former boyfriend spent nearly $3,000 at a celebrity auction Saturday scooping up lingerie once worn in a Playboy shoot by the late playmate.

Birkhead said he is trying to make sure his 1-year-old daughter, Dannielynn, has something to remember her mother by.

"I have a lot of history I have to put together that she doesn't really know about," Birkhead told The Associated Press. "Playboy was such a big part of Anna's career."

Birkhead bought a pink bustier for $1,800 and a white negligee for $1,000 at the auction, run by Julien's Auctions and held at Planet Hollywood Resort and Casino on the Las Vegas Strip.

He was awarded custody of Danielynn after Smith died from an overdose of prescription drugs in February 2007. She was 39.

Birkhead said he hoped the items would help his daughter learn her mother's life story - when she's old enough.

"You know, it's not something I can show today, but something down the road," Birkhead said. "It's not going to be in any bedtime stories anytime soon."
