Mary-Kate Olsen and Ashley Olsen looked casually chic as they stepped out together for a Thursday coffee run in New York City. The actresses, 36, wore long black coats and scarves.

Consider the bizarreness of the Olsen twins' life. They're born in June 1986 on, as it happens, Friday the 13th. Ashley arrives first and two minutes later, there's Mary-Kate - non-identical Gemini sisters for Trent, aged two. When they're about seven months old, one of those friends with which this sort of story is always populated suggests that the Olsen parents - Dave, a mortgage banker, and Jarnette, a former ballet dancer - send photos to a casting director. A television show in pre-production needs a baby and Californian labour laws mean that one tot is more usefully played by twins.

I always loved you, You always had a lot of style. I'd hate to see you on the pile, Of ‘nearly-made-its' You've got the essence dear, If I could have a second skin, I'd probably dress up in you
