In October 2019, Tom Riley supported his wife, Lizzy Caplan, while attending the season two premiere of her Hulu series Castle Rock held at the AMC Sunset 5 in Los Angeles.

The then-37-year-old actress donned a peach off-the-shoulder dress from the Area Spring 2020 Collection that appeared slightly too long. She paired her floor-length gown with matching peach eyeshadow and a red-orange lip.
Her co-stars Elsie Fisher, Matthew Alan, Tim Robbins, Yusra Warsama, Paul Sparks, Isayas Theodros, Barkhad Abdi, and co-creator Dustin Thomason joined her at the event.

Elizabeth Anne Caplan, who dated actor Matthew Perry from 2006 to 2012, met Tom Riley in January 2015 while filming the British-American war thriller Allied in London.

Best known for his leading roles as Leonardo da Vinci in three seasons of the historical fantasy drama series Da Vinci’s Demons, he began acting in his hometown at the age of four.
They made their red carpet debut as a couple at the Prague Opera Ball in February 2016. The black-tie event raised much-needed funds for UNICEF. She looked stunning in a black lace Dolce & Gabbana dress.

After Riley proposed in New York City, the pair announced their engagement in May 2016. In September 2017, they were married in a dreamy Italian wedding on the Amalfi Coast. They welcomed a son, Alfie, in 2021.
