Katharine McPhee Foster is one hot mama that knows how to party!
The 37-year-old actress isn’t letting motherhood get in the way of her summer vibes! Katharine shared a summer snap of herself enjoying an adult beverage while wading in the kiddy pool on Monday, June 28. She joined her adorable baby son, Rennie… the kiddy pool would be weird if she weren’t. The songstress sipped a Blue Moon in a sporty bikini top as Rennie played in the water with the help of his trusty Summer Sea baby float (she has all the coolest baby gadgets).
“mommy & me,” the cool mom simply captioned her post.

She Is All Of Us
Katharine may just be the most relatable celeb mom ever, and her followers sounded off about how much they love the pic and her sense of humor.
“Very cool!” one impressed fan wrote, while another said, “you’re the best mama! ❤️”
“Wow you are Gorgeous 😍 your husband is a lucky guy,” a third follower commented.
Several fans commented on the star’s cool summer gear even though not everyone would use it the same way. “Where did you get that pool? I need the same kind of pic, but with my dog and I 😫❤️,” one funny follower joked.
It’s Her Anniversary With David Foster

Interestingly enough, she shared the pool beer-pounding pic on her 2nd anniversary with super music producer David Foster. McPhee became McPhee Foster on June 28, 2019, when she married the 71-year-old at the St. Yeghiche Armenian Apostolic Church in Kensington, London. “Is this how you’re spending your anniversary?” one musician friend jokingly asked the funny mother. It seems like a pretty dang good way to spend an anniversary!

Katharine Annoyed David By Revealing Rennie’s Name

McPhee Foster seems like the perfect mother/wife, but she did tick off her famous hubby when she let their son’s name slip on the “Today Show.” She admitted David was “annoyed” when she revealed that the name was Rennie and that it is an old Foster family name. “My husband was kind of annoyed,” Katharine confessed on SiriusXM’s “The Jess Cagle Show” at the time. “I said, ‘What was I supposed to say [when asked]?’ Nothing?”
“We don’t want to be, like, that pretentious over the name,” she continued but said that she understood Foster’s annoyance. “It’s the only kind of thing you can hold onto that feels private.”
