Masterchef judge John Torode is dating actress Lisa Faulkner, the winner of the celebrity version of the show.
The pair were snapped by the Mirror leaving John's home together on Friday evening, and were later seen leaving the property again on Saturday afternoon.
The couple originally met when Lisa took part in the cookery programme and have remained friends since. Lisa has gone on to have a successful career in the kitchen, releasing a cookery book and working with John on one of his London restaurants.

Lisa has recently split from her husband, former Eastenders actor Chris Hoghill, with friends saying their decision to break up came from strains in their relationship. John is himself getting over a split, as he also parted ways with his wife Jessica in January.
A friend of Lisa told the newspaper: "Lisa and Chris split up several months ago. She has been friends with John for a long time. But in recent weeks they have become close and are spending more and more time together.
"It is early days but Lisa's close family and friends are aware of the relationship and just want her to be happy."
The source added that Lisa and her former husband are keen to stay on good terms for their adopted daughter Billie. John also has four children of his own from two previous marriages.
