“David posted this while playing games on my phone,” McPhee wrote. “Not sure why or how he chose it but I’m not complaining.”

In August, theAmerican Idolalum opened up toEntertainment Tonightabouttaking Foster’s last nameafter their wedding.

“I’m a romantic, I’ve always loved the idea of taking [his last name],” she said. “It’s sort of a traditional thing that still exists in our society, but some people don’t take their spouse’s last name anymore, so, I like the idea of it. I think it’s romantic and it’s a great last name.”

McPhee added that her favorite part of married life to Foster is the quality time the two spend together.

“There’s not arguing, no drama,” she told the outlet. “It’s just easy, that’s how it should be.”
