New Delhi, Feb 20: Hotel heiress Paris Hilton is desperate to woo back her former lover Benji Madden, it has emerged.

The stunner - who parted ways with the `Good Charlotte' rocker last November - has gone green with envy after seeing snaps of Benji spending Valentine''s Day with singer Katy Perry, reports the China Daily.

A source said: "Paris still has very strong feelings for Benji and seeing those pictures has really hurt her - especially as they were taken so close to her birthday.

"She is determined to get Benji back and she is not going to let anyone or anything stand in her way."

Benji and Katy spent the romantic day together in Las Vegas, although the ''Hot n Cold'' singer has since claimed they are just good friends.

She said: "It''s two pseudo famous people sitting next to each other... doesn''t mean we were bumping uglies! You know I don''t just do that with anyone!

"I was there celebrating a really fun show and a boozy Valentine''s Day with all my good friends. We were like a group of 25! Benji is a nice young fellow, but my heart really belongs to my cat." (ANI)
