Lindsay Lohan presenting the World Music AwardsLindsay Lohan and Paris Hilton look like they’ve well and truly fallen out again after just a month of reconciliation.

The pair announced the end of their year long feud with a partying weekend in Las Vegas last month but Lindsay is reportedly mad at Paris after rumours that Paris has a thing going on with Lindsay’s ex Harry Morton.

According to the Sun, the two stayed well clear of each other at Wednesday’s World Music Awards which Lindsay was emceeing, with Paris presenting an award.

An inside source told the newspaper: “Lindsay hid in her trailer the whole time and didn’t come out to speak to anyone.”

“When Paris walked past the window, she held her bag up to her face so Lindsay couldn’t see it was her.”

“She couldn’t have been more obvious.”

According to the Mirror, Paris later urged her friends at the event to sneak into Lindsay’s dressing room and hide her clothes.
