The couple, which wed last year (19), has been staging daily mini concerts on social media while in self-isolation during the coronavirus pandemic, and on Wednesday (April 01), the "Smash" star revealed she had turned barber for her man.
After introducing viewers to the livestream, McPhee recapped what they had been up to since their last online gig.
"The update is I cut your hair," she said as she turned to Foster, and then pulled out a pair of scissors to trim his locks a little further.
"She did an amazing job - look at this!" Foster gushed, as McPhee explained, "It's just a minor adjustment."
"She did a great, great job," the 70-year-old continued. "My hair was getting so long. I was starting to look like Einstein!"
Foster and McPhee's nightly shows, which take place around 8.30pm EST, can be viewed online at https://www.instagram.com/katharinefoster/.
