It’s a tale as old as time: Boy meets boy, boys marry and father five kids, boys break up when one falls madly in love with their daughter’s ex-boyfriend, and they all live happily ever after.

Such is the fate of Britain’s “first gay dads,” who have gone public with their unconventional family dynamic after one of them fell “head over heels” for a guy who dated their 19-year-old daughter. Now they all live under one roof — a $7 million mansion in Florida.

Barrie and Tony Drewitt-Barlow made headlines in 1999 when they became the first British same-sex couple to be named as parents on a birth certificate, for their newborn twins Saffron and Aspen. It was a landmark court ruling that ushered in a new era for LGBTQ parents in the UK.

After setting up their own lucrative surrogacy company, the couple had three more children — Orlando, born in 2003, and twins Jasper and Dallas born in 2010.

32 years into their relationship, Barrie, 50, and Tony, 55, have decided to split. Barrie now plans to marry Saffron’s ex-boyfriend, Scott Hutchinson, 25.

Tony and Saffron have both reportedly given their blessing, and they all plan to live as one big happy family.

Speaking with The Sun, Barrie explained:

“I’ve fallen in love with Scott and he has done the same. I feel stupid at my age to have these feelings about someone other than Tony and half my age. But when you know something is right, it’s right. We have not made definite plans but I would like to marry Scott.

“I’m not having a mid-life crisis — if I was having one I’d buy myself a Porsche 911.

“This is the real deal. But not everyone will get it, as our living arrangements are unorthodox — I feel like I’m living in a commune, we are all still living together.”

He continued:

“Our children are still in a stable set-up, more so than many other families have. But now Dad’s got a new fella and we are one bigger happy family instead.”

Barrie also explained that Scott and Saffron’s relationship was never sexual. See? Nothing weird here.

“Saffron and Scott had been split for many months and this was something totally unexpected,” he said. “Saffron and Scott were always just friends — their relationship was puppy love.”

“They never had a sexual relationship as she was so young. Scott had made no secret of being bisexual which was why their physical relationship never developed.”

So wait, which was it… They never had sex because Saffron was “so young” (19) or because of Scott’s bisexuality?

Whatever the reason, Barrie and Tony sat Saffron down at the dining table to tell her the news.

“Of course she was annoyed at first but Tony said: ‘This is a good idea. You can see how Scott is with Daddy, he likes him.’ There were no rows. We just talked as adults.

“Saffron sees how happy we are and she has accepted it.”
