While it was undoubtedly a difficult day for Rizzo — who met Saget in 2015 and married him three years later in 2018 — she found a sweet way to keep her late husband close at Friday's service.
The Eat Travel Rock blogger, 42, threaded a gold chain through her late husband's wedding ring and wore the sentimental piece around her neck.

"It was a great relationship and they were perfect for each other because they're just two neurotic people living under one roof," Young said. "I mean, they're awesome together and they're hilarious together and she's like, the perfect person that could handle Bob."
"Bob was so happy and he talked about her all the time," he continued. "It hurts because as much as she has to share him with the whole world, she knows damn well that he was hers and that was it and he was all about her. He loves her to death."
