No, Kate Moss has not gone plum crazy. She’s just crazy for plums, apparently. And making them into jam.

The supermodel is reportedly turning her preserve-making hobby into an official line of jams called Kate’s Damson Jam (a damson is a type of plum). Even daughter Lila Grace, seven, is helping out to make jam with mum up at their Cotswold estate, according to UK tab The Sun.

“It started as a hobby, but she’s taking it a lot more seriously after glowing feedback from friends and family,” a source told The Sun. “She’s hoping her plum conserve will be a hit with the public.” The paper also reports that Moss has asked Sir Philip Green and Simon Cowell for their feedback and help in stocking her plum product.

Of course this isn’t the first we’ve heard of Kate’s culinary leanings. Last April she was allegedly in talks with Green to pen a cookbook–which we’ve yet to see.
