Paris Hilton may not have time for The Simple Life any more, as the jet-setting heiress parlays her celebrity fame into a branding bonanza.

The blonde hotel heiress, whose hit reality series on Fox has been attracting audiences of nearly 10 million viewers, has launched a jewellery line on Amazon.com that is the start of a master marketing blitz.

Hilton, 23, is filming National Lampoon movie comedy Pledge This! due out next year, cutting a pop-rock album, and also intends to put the Paris Hilton brand on clothing, perfumes, makeup and shoes - for starters.

"I'm not sure yet about The Simple Life," Hilton told Reuters in a telephone interview.

"I'm finishing an album. They want to do a third season, but I don't know if I have time."

The 20th Century Fox Television producers of the show were not immediately available for comment.

Hilton's 198-page memoir, Confessions of an Heiress: A Tongue-in-Chic Peek Behind the Pose, hits book stores next week in the United States.

The socialite and model landed the Fox show after massive exposure from a sexually explicit home video of her and her then boyfriend that hit the Internet three years ago,
