The Big Bang Theory star Kaley Cuoco and Ozark actor Tom Pelphrey are celebrating a major milestone. On Tuesday, April 21, 2026, the couple marked their fourth anniversary with a series of emotional tributes, reflecting on a journey that began with a “love at first sight” encounter in New York City.
Cuoco, 40, took to Instagram to share her gratitude for their life together, which now includes their daughter, Matilda, and a recent engagement. “I met you 4 years ago today, and wow I could never have dreamt this life up,” she wrote. “I love you through every high and low, every laugh and tear, with every ounce of my being!
A Romance Born at the ‘Ozark’ Premiere
Pelphrey, 43, mirrored the sentiment by taking fans back to the very beginning. The pair first met on April 21, 2022, at the Paris Theater in NYC during the premiere of Ozark Season 4.
“As Laura Linney reminds me, ‘Ozark—the gift that keeps on giving.’ Indeed it is true,” Pelphrey penned in a heartfelt note. He thanked Cuoco for “the cheesy shit and the hilarious things,” noting that their bond has only strengthened through the “hard times and all the seasons.”
