Katharine McPhee Dropped Another Big Hint About When She Will Marry David Foster

Katharine McPhee and David Foster got a marriage license in Beverly Hills last month, but did they also get married?

If they're not already married, they have until August 15 to do so in order for that license to be valid. And according to the California Department of Public Health, after obtaining either a public or a confidential marriage license, a couple must be married in California in order to be considered legally married — even if they want to have a summer ceremony in, say, London, as has been rumored for McPhee and Foster.

McPhee is done with her London theater run in Waitress and had a crazy bachelorette party out there, so it'd be easy to believe that they fell in love with the city while she was working there and would want to get married — or have their official ceremony — there. (There's also no reason that they couldn't have a wedding in the U.K. and make things U.S. official upon their return, or even pop back stateside to get officially married and then jet back off to the U.K. for an event.)

Then there's this telling clue she offered during her last performance:

"I would stay here and do the show longer,” McPhee said onstage on June 15. “But my fiancé, who I’m about to marry, he’s endured enough separation.”

So, is this couple already a Mr. and Mrs.? Don't quote our magic eight ball, but all signs point to yes.
