David Foster is standing behind his new fiancee Katharine McPhee and her feisty responses to the internet hate they've received after announcing their engagement earlier this month.
"Of course" he's proud, Foster told USA TODAY. "She's my girl."
Foster, 68, popped the question to McPhee, 34, during their European vacation earlier this month, and she made the news public on July 3. After days of buzz about the engagement, some critical of the match, McPhee tweeted a pointed response on July 6.
"Y’all should be worrying more about registering to vote and midterm elections than who’s marrying me," she wrote. "Thank you for coming to my TED talk."
Speaking to USA TODAY as part of a longer conversation about his many current projects — including a new Joe Jonas song "Party Time" he wrote for the "Hotel Transylvania 3" soundtrack, an album he co-wrote for Michael Buble and newly-added dates on his Hitman tour — Foster said that McPhee's response just "is who she is."
"And you know, obviously all of us have to balance what's going on out there," he said. "Social media, it's just the greatest thing in the world and also deadly. You know if you really wanted to deal with all the haters, I've had so many haters since social media started, and you just have to ignore the clutter and live your life, and I'm just living my best life right now."
As for the rest of their wedding-planning news, Foster directed interested fans to McPhee's social media feeds.
"I'll let you read about it on social media," he said. "I'm just really happy."
