LAS VEGAS (AP) -- 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 in Las Vegas, scooping up lingerie once worn in a Playboy shoot by the late playmate.
Birkhead tells The Associated Press that "Playboy was such a big part of Anna's career" and it's something that will help his 1-year-old daughter Dannielynn learn her mother's life story when she's old enough.
He bought a pink bustier for $1,800 and a white negligee for $1,000.
Birkhead was awarded custody of Dannielynn after Smith died from an overdose of prescription drugs in February 2007. She was 39.
