ASHLEE SIMPSON has sparked speculation she's making lyrical attacks on fellow teen star LINDSAY LOHAN with her new single BOYFRIEND.

Reports have long suggested the two beauties have been feuding because PIECES OF ME singer Simpson wooed actor WILMER VALDERRAMA away from Lohan.

And while Simpson has always denied dating Valderrama, she has penned a cheeky song which many believe is directed at Lohan.

Simpson tells MTV News, "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."
