Famously private couple Katharine McPhee and David Foster, who shocked fans with a surprising appearance together on the red carpet at the 2018 Met Gala back in May, are finally loosening up. Case in point? The pair engaged in a rare display of digital PDA on social media this week.

While on vacation in Israel together, McPhee and Foster have been commenting like crazy on each other's photos and posts. But on Monday (June 25), McPhee left one comment that got followers really buzzing, calling her beau "so so handsome" and telling him she loves him in the comments section of a photo he shared.

Meanwhile last month, Foster gushed about his girlfriend's turn in Waitress: The Musical, sharing a photo of McPhee on his Instagram page and writing, "Must see! #Brilliant"

McPhee, 34, and Foster, 68, first met in the mid-2000s, when the record producer produced one of the American Idol alum's early singles. Dating rumors sparked in May 2017, and by December 2017, the couple had been spotted smooching in Beverly Hills and Paris. In March 2018, the pair attended Elton John's Oscars viewing party together.
