ASHLEE SIMPSON - SIMPSON DENIES ACCUSATIONS SHE PHYSICALLY THREATENED LOHAN

Singer ASHLEE SIMPSON has denied accusations she threatened to attack LINDSAY LOHAN because the MEAN GIRLS star refused to let her into her party on Saturday night (04JUN05).

The pair have allegedly been embroiled in a bitter feud since Lohan accused Simpson of "stealing" her ex-boyfriend, actor WILMER VALDERRAMA last year (04).

But the rumours have been fuelled following reports the pair almost had a "catfight" after Lohan banned Ashlee and her sister JESSICA from coming to her bash at Los Angeles' Standard venue after the MTV MOVIE AWARDS.

The Simpsons went to JIMMY FALLON's party at Los Angeles' Argyle Hotel instead, and reportedly hit out at Lohan who arrived later.

But they overcame their differences after Lohan explained it was a mistake that they were not let into her party, reports website PAGESIX.COM.

Lohan's representative confirms the mix-up: "Their names got misplaced on the list."

And Ashlee's spokesperson denies claims the PIECES OF ME star threatened Lohan, adding, "Ashlee and Jessica had a great time at Jimmy's party, which was the hottest one of the night."
