Pop star ASHLEE SIMPSON has slammed claims the lyrics of her new single BOYFRIEND are aimed at former love rival LINDSAY LOHAN.

The singers have been embroiled in a bitter feud since Lohan accused Simpson of "stealing" her former boyfriend WILMER VALDERRAMA, of THAT 70s SHOW fame, last year (04).

The PIECES OF ME singer insists the scathing chorus, where she sings "I didn't steal your boyfriend", is not an attack on the newly blonde singer/actress.

She says, "It's not about one person in particular, it's just something every girl can relate to.

"It's a song about (how) every girl out there sometimes thinks you stole her boyfriend. It's just making fun of that."
