and It Feels So 2007

Like Hollywood's version of the Camp David Accords, Paris and Nicky Hilton reunited with their old long lost pal Lindsay Lohan at a restaurant in the Palisades last night.

It appears Paris and Linds are super serious about rekindling their friendship -- they also partied together last weekend at Hilton's Malibu beach pad.

But this time, they made sure everyone could SEE the reunion ... and HUGGED IT OUT at the end of the night -- right in front of the cameras.  

UPDATE: We're told the reunion wasn't planned -- the two just happened to bump into each other while going to dinner with different people.
