Lily Allen is back from her crazy week in Cannes now – but that doesn’t mean the fun has to stop. She showed that she and her ex-boyfriend, Ed Simons from the Chemical Brothers, are still on friendly terms by having a cosy lunch with him (they even made silly walrus faces with their chopsticks, just like we do!)… but then spent the afternoon with fellow music man Mark Ronson. Well, well, well. Lily and Mark looked like an old married couple as they shopped at their local Tesco together before renting a DVD from Blockbuster. Since Mark’s meant to be dating Daisy Lowe, we assume things are strictly platonic between him and Lily, but we’re still jealous of her leisurely life…
