Rekindling Their Showmance

Paris Hilton and Britney Spears are back “on.”

The former BFFs were partying it up together on Saturday night, in celebration of Unfitney’s 26th birthday.

On Sunday, Hilton stopped by the Sydney Michelle store to pick up some girly things for her pal.

Paris also stopped by a store to collect gift wrap and yet another to pick up some food.

Hilton then headed over to the former singer’s mansion where she reportedly spent the day with Britney, her two sons and her mom.

How long until Britney’s back in rehab????
