Desperately seeking relevance?

Former rivals Paris Hilton and Linsday Lohan -- who both avoided long-term prison time recently -- have rekindled their friendship.

After a falling-out in 2006, when Lohan hooked up with Hilton's ex-beau Stavros Niarchos, "they've put their past behind them and have bonded over all the stuff they have in common," an insider tells Us Weekly. "They both feel screwed over by Hollywood and their older friends."

But don't expect Lohan, 25 --who was photographed leaving Hilton's Malibu home at 5 a.m. July 31 -- to order matching necklaces for her and heiress, 30, just yet.

"Secretly I think they're only hanging out because they know it makes a better picture," adds the source. "They want to be superfamous again!"
