The pair were pictured sharing a cosy roadside picnic together and walked arm in arm in casual outfits back to her car.
Dressed down in a navy gilet, white T-shirt and trainers, events and production mogul Alex protectively pulled the TV chef in close to him as they shared a giggle.
Eating sandwiches on a quaint picnic table, Nigella looked radiant in a polka dot maxi-dress, black shades and cross-body bag.
Celebrity chef and ‘mee-cro-wah-vay’ queen Nigella, 62, has had several high profile relationships in her life.
The mother-of-two has children Cosima Thomasina, 26, and Bruno Paul, 24, from her relationship with first husband John Diamond.
Meeting at The Sunday Times where they both worked in 1986, the journalist died of throat cancer in March 2001 at just 47 years old while his wife was filming Nigella Bites.
The couple were married for nine years after tying the knot in Venice in 1992.
Two years after her first husband’s death, Nigella married art collector Charles Saatchi in September 2003.
Married for 10 years, the famous relationship was renowned for being tumultuous and ended in an extremely public divorce in 2013.
The art expert is now in a relationship with fashion stylist Trinny Woodall.
Since her last marriage, TV chef Nigella has been tight-lipped when it came to her romantic life, with fans left wondering whether she was dating or not.
The famous foodie is currently on a 16-city US tour to promote her new book Cook, Eat, Repeat: Ingredients, Recipes and Stories.
Her 12th cookbook landed on US shelves in April 2021 and now she is showing up in person to deliver ‘the rhythms and rituals of life spent in the kitchen.’
Nigella Lawson’s representatives declined to comment when approached by Metro.co.uk.
