There probably aren't any recent ones though I could definitely make them. She's from S Club 7 and they were on the show Primeval together. But honestly, anyone in their late 30's who is quirky and blonde would work as blonde is definitely his type.
They split up because they realized the chemistry just wasn't there anymore. It was a very hot and heavy romance, as young love usually is. He's from England, and they met when she was there studying abroad. She came home, he followed her shortly after because they missed one another. Quickly got married, struggled a bit, fought a bit, called it quits. They're amicable on a certain level -- mostly because for the longest time, she was the only person he knew here and after going through all the stuff to get his citizenship, he didn't want to just leave. So they've remained awkwardly friends since -- less awkward now as it's been more than a decade. She teases him for being something of a hermit but it's all in good fun.
