Why Prue Leith Decided to Publicly Reveal 13-Year Affair With Husband of Her Mom's Best Friend

Prue Leith will not underbake the truth.

That's why The Great American Baking Show: Celebrity Holiday judge admitted in her 2012 memoir Relish: My Life on a Plate that she had a 13-year affair with her first husband, Rayne Kruger, while he was still married to her mother's best friend, Nan Munro. 

"I thought when you're writing an autobiography, what you should be doing is writing the interesting bits and leaving out the boring bits," Prue told E! News' Francesca Amiker in an exclusive interview. "Nobody's interested in your achievements. They're interested in your failures."

Ultimately, Rayne split from Nan in 1974 and married Prue in the same year. The parents of Danny Kruger, 49, and Li-Da Kruger, 48, were together until Rayne—who was 20 years Prue's senior—died at age 80 in December 2002.

"Love is the most important thing in anyone's life," she shared, "and to just decide to leave out the most important man in your whole life—who's been your lover, your chairman, your husband, the father of your children—it would be ridiculous." 

While the 83-year-old knew including the affair in the book would raise some eyebrows, she did not expect her confession to turn into the showstopper that it did. 

"It upset my children a lot," she said of attention on that particular part of her memoir. "They had read it all before and they knew it was just part of the whole story."

However, the Great British Bake Off star said the family has since gotten "over it."

"It's not the end of the world," she joked, before noting with a laugh that "it's my own fault."

"If I go public on something, I can hardly complain if somebody talks about it," she quipped. "I think it's a good piece of writing. It's the truth and I was trying to write my life, so what I did was correct."

These days, Prue is enjoying the sweet life with her second husband John Playfair, who she wed in 2016.

"He's very good company," she shared. "He makes me laugh and he's very gregarious. He gets along with everybody."

The Great American Baking Show: Celebrity Holiday is out on The Roku Channel now.

Some fans might not be familiar with the show's first-ever champion Edd Kimber, as season one of The Great British Baking Show never aired in the U.S. or appeared on Netflix. But the baker has been up to a lot since his time on the show in 2010, having written for several publications, appeared on numerous TV shows and published six cookbooks.

Like with season one, season two of the series also never aired in the U.S. or on Netflix. In addition to publishing a cookbook, the show's second champion Jo Wheatley continues to share her latest recipes with fans on her successful food blog, Jo's Blue AGA.

Trading in his apron for his dancing shoes, season three winner John Whaite went on to compete on season 19 of Strictly Come Dancing (the U.K.'s equivalent to Dancing With the Stars), and came in second place. But that's not all he's done. The Star Baker has opened up his very own cookery school and published several cookbooks.

Frances Quinn's gorgeous-looking bakes earned her the title of season four champion in 2013. Since her time on the show, the 40-year-old has come out with a cookbook and started her own baking blog. She even baked the world's largest Jaffa Cake earlier this year.

Grandmother of nine Nancy Birtwhistle is just as passionate about baking now as she was during the show's fifth season in 2014. Along with being active on social media, she has followed in her fellow competitors' footsteps and created her own blog and written several books, both about baking and how to live an eco-friendly lifestyle.

Season six winner Nadiya Hussain went from competing on a TV show to having several of her own. She has starred in multiple cooking and baking shows as a host and judge, including GBBS's U.K. spinoff Junior Bake Off. Not to mention, she baked Queen Elizabeth II's 90th birthday cake in 2016.

Not only is Candice Brown a baker, cookbook author and season seven winner of GBBS, but she also earned the title of restaurant owner with the opening of her pub, The Green Man, in 2019.

After winning the competition's eighth season in 2017, Sophie Faldo turned her passion for baking into a job by launching her very own baking business, Sophie Faldo Couture Cakes.

Rahul Mandal used his skills as an engineer to secure his victory on the show's ninth season. He continues to balance his passion for science with his love of baking and shares his latest creations with fans on Instagram. His first cookbook, Showstopping Cakes, will be released this October.

Like many GBBS winners, season 10 champ David Atherton has released multiple cookbooks, including children's cookbooks aimed at helping kids learn basic cooking and baking skills. When's he's not posting his latest creations on Instagram, he's sharing sweet pics of him and his partner, Nik Sariyski.

At the age of 20, season 11 champion Peter Sawkins became the show's youngest-winning contestant in 2020. Two years later and he already has one cookbook under his belt with a second on the way. Peter continues to share his love for baking on Instagram, and continues to keep in touch with several of his fellow GBBS contestants.

Giuseppe Dell'Anno is the show's most recent winner, impressing the judges with his Italian bakes on season 12 in 2021. Only a year out from his win, he's already written a cookbook—set to be released this December—and made a few television appearances. And like Peter, he enjoys meeting other former contestants from the show.
