Katharine McPhee, 39, and David Foster, 74, kiss on the Hallmark float during Macy’s Thanksgiving Day Parade

David Foster and his fifth wife, Katharine McPhee Foster, got into the holiday spirit Thursday by kissing on a float during the 97th annual Macy’s Thanksgiving Day Parade in Manhattan.

At 74, the legendary composer is 35 years older than the beautiful singer, but on June 28 they celebrated four years of marital bliss.

From May to December, the couple had fun atop Hallmark Channel’s Heartwarming Holiday Countdown float, which featured a 3D Christmas Advent calendar with large toys in each booth.

At one point, Katharine — who gets 878,000 monthly listeners on Spotify — sang a cover of J. Fred Coots and Haven Gillespie’s maroon 1934 Santa Claus Is Coming to Town during the festivities.

McPhee and Foster were essentially promoting their holiday album, Christmas Songs: The Complete Collection, which was released on October 20.

Things are still going well! At 74, the legendary composer is 35 years older than the beautiful singer, but on June 28 they celebrated four years of marital bliss.

The Los Angeles resident and Canadian grandfather of seven were both bundled up in winter coats to combat the Big Apple’s crisp fall weather of 42 to 55 degrees Celsius during the vibrant outdoor event.

Katharine showed off her slim 6-foot figure in a gray knit turtleneck, tucked into a black midi skirt with a thigh-high slit and black boots selected by stylist Monica Rose.

On Wednesday night, David and McPhee brought their two-year-old son Rennie David to The Rockettes’ Christmas Spectacular at Radio City Music Hall for the first time.

“My favorite holiday tradition is seeing the Radio City Rockettes. This was Rennie’s first year and it was so much more fun!’ the founder of KMF Jewelry – who has 1.8 million social media followers – gushed over Instastory.

“If you’re in NYC and have kids, I highly recommend bringing them along this holiday season.”

Katharina said On with Mario Lopez on Wednesday: ‘This Christmas season will be a lot of fun, because last year he was still a bit of a baby. But now he’s talking about Halloween and Thanksgiving and Christmas and Santa Claus, so he’ll really get it this year. So I’m going to have a lot of fun with that!’

Back on October 15, McPhee shared a video in which little Rennie shows his impressive drumming skills together with his coach.

The toddler has clearly inherited real talent and rhythm from his musical parents.
