And what's Paris Hilton going to do for the bottom line?

Investors in

Parlux Fragrances

(PARL)

may be asking that question after the Ft. Lauderdale, Fla. company Thursday said fourth-quarter profit doubled, triggering an attention-getting gain in its stock price.

Shares rose $1.75, or 21.7%, to $9.78 in trading volume almost four times its daily average of about 169,000 shares.

Net income rose to $2.5 million, or 24 cents a share, from $1.1 million, or 12 cents a share, a year ago. Revenue rose by more than a third to $19.6 million.

Parlux Fragrances describes itself as a manufacturer and international distributor of prestige fragrances and holds the licenses to manufacture and distribute the designer fragrance brands of Perry Ellis, GUESS? and others. The company recently signed a worldwide license with the American pop icon Paris Hilton to manufacture and distribute a fragrance under her name. A launch is planned for later this year.

For the full year, Parlux earned $6.3 million, or 63 cents a share, on revenue of $80.6 million, versus $5.5 million, or 54 cents a share, on revenue of $72.3 million.

The company has a market capitalization of $77.8 million.
