This week is bursting at the seams with celebrity birthdays - so much so that we were regretfully forced to leave some famous faces out of our gallery. Let's hope those who didn't make the cut - including such luminaries as Belinda Carlisle, Casey Affleck, Mark Knopfler, Grace Adams-Short and... ahem.. Rumer Willis - will one day find it in their hearts to forgive us. In the meantime, the lucky few who did make it (and they include two of the world's biggest stars) are just a click away.
