If the royal box at Wimbledon yesterday taught us anything (aside from the fact that David Cameron's got some nerve) it's that we love a celebrity spot.
What we want to know from you, dear readers, is your best/worst/weirdest/funniest/cringiest celebrity encounter.
Perhaps you ran into Liz and Phil nipping down to M&S for G&T supplies. You might have seen Clare Balding riding a donkey down Regent Street. Or maybe you espied Jeremy Corbyn sobbing behind a skip.
Let us know in the comments — we're putting the best ones in an article soon.
