Larry Birkhead spent nearly $3,000 on Anna Nicole Smith’s underwear over the weekend.

The photographer, who fathered a daughter, named Dannielynn, with Anna Nicole, purchased a pink bustier once wore by the late Playboy Playmate for $1,800 and a white negligee priced at $1,000 at a celebrity auction in Las Vegas on Saturday.

Larry claims he bought the items as heirlooms for the couple’s young daughter, stating that the purchases will help 1-year-old daughter Dannielynn learn her mother’s life story when she’s old enough.

“Playboy was such a big part of Anna’s career….You know, it’s not something I can show today, but something down the road…..It’s not going to be in any bedtime stories anytime soon.”
