Based on her Instagram, Katharine McPhee seems to be in good spirits, considering she filed for divorce from Nick Cokas just last week. 

The former "Smash" star posted a video of her with Kellie Pickler enjoying a girls' vacation in Mexico.

Katharine and Kellie are seen posing in a cabana and smiling for the camera, saying "Hola!"

On May 22, Katharine's rep released the following statement: "After six years of marriage, and having been separated for the past year, Katharine McPhee has filed for a dissolution of marriage from Nick Cokas. The two have an amicable relationship and will remain friends. They ask that people respect their privacy during this time."

A source told E! News that Katharine "is in a really good place right now."

Katharine and Nick met in 2005 when they performed in a L.A. production of "The Ghost and Mrs. Muir." They got engaged two years later and married in Beverly Hills on Feb. 2, 2008.
