It is a special week for Katherine LaNasa.
On Monday, August 18, the instant-favorite The Pitt star celebrated her 13th anniversary with her husband, the star of yet another fan-favorite show, Melrose Place's Grant Show.
The couple tied the knot in 2012 after first crossing paths in 2006, and share one daughter, Eloise, who is 11.
In honor of their special day, Katherine took to Instagram and shared a round of photos of the two, starting off with a black-and-white selfie.
More black-and-white photos followed, including some of them dressed up in cocktail attire, walking around Los Angeles, at a bowling alley, and more.

Grant was previously married to Scottish actress Pollyanna McIntosh from 2004 to 2011. One year after marrying Katherine, he told People that the two were trying to have a child together. "We are working on it — practice, practice, practice," he said at the time, noting: "We're both older, so it's a little difficult, but we're working on it."

"She'll do things that are not necessarily things that she wants to do that I like to do — like she'll go play golf with me — and then I'll do things with her, like go shopping. And then you know, you just have to make sure to keep doing it," he said.
