Prior to their stop in Greece the couple enjoyed some time in Lake Como, Italy.

The couple - who began dating in spring 2017 - were spotted getting a marriage license in Beverly Hills last month hinting they plan to tie the knot shortly. 

In the state of California, a marriage license expires 90 days after it's issued.  

Before their European getaway the actress just finished her run in the musical Waitress in London.

At the end of her final performance Katharine told the audience, 'I would stay here and do the show longer, but my fiancé, who I’m about to marry, he’s endured enough separation.'

'We both have,' she continued. 'FaceTime is our best friend.'

Meanwhile, David’s daughter Sara said she thinks Katherine will be a 'great addition' to the family.

'She's great. She's a great addition. You know I've learned to not rule anything out [like David and Katherine having children]. I think anything is possible at this point,' she said. Who knows? ... She's wonderful. The other day she was like, "I got you a facial," and like that's so cool.

'My dad loves love and my dad loves commitment. My dad's always been married. He's never been single really. He's a real commitment, marriage kind of guy and I'm happy for him.'

Katharine was previously married to Nick Cokas for nearly five years before a divorce was finalized in February 2016, while David has been married four times and has five daughters and seven grandchildren.
