Justin Timberlake has become obsessed with baking.
The hitmaker has been impressing his wife, Jessica Biel - whom he married in October - after his grandmother Sadie Bomar taught him her cooking secrets.
Sadie told The Sun Sunday newspaper: "Justin comes in the kitchen with me when I'm in there because he wants to know how it's done.
"He comes in, puts an apron on and he wants to learn. Jessica is a lucky girl because he makes her good, home-cooked pies. I've taught him well."
The 32-year-old "loves" recreating his grandmother's trademark pastries for his new bride and is willing to improvise with changes to the recipes.
Sadie said: "I've taught Justin to cook. He loves my pies and now he makes my three-layer pie.
"It's got a chocolate layer, but Justin makes it with butterscotch. I have also taught him to make an apple pie and a pecan pie, a sweet potato pie and also a coconut one. He loves them."
Justin made his return to music in January after a long hiatus and his new album The 20/20 Experience hit the top spot in the UK Album Chart on Sunday.
