Tinseltown- STEAMY Paris Hilton is bracing herself for a second sex video scandal, the News of the World can reveal.

Stills and clips of her bonking ex-lover Nick Carter, the former Backstreet Boy, were on a laptop that vanished in the recent break-in at her Hollywood home, she has told pals.

Police are now claiming a duplicate key was used- with the intruder damaging a wire screen to make it look like a forced entry.

They say as well as the tapes, hundreds of thousands of dollars were stolen in cash and jewelery

A source close to Paris, 23-whose taped romps with ex Rick Salomon are now public property-said the hotel heiress is “terrified of more exposure”.

“She’s bracing herself for further embarrassment,” said the source. “Nick and Paris loved making sex tapes.”

But Nick, 24, who split with Paris days before the break-in, says: “There are no sex tapes of me and Paris.”

Despite her “outrage” over the Salomon sex tape, millionairess Paris has profited handsomely from it after agreeing to share money from sales of it with her ex.

The deal has netted her £250,000 so far, most of which she is said to have donated to charity.
