As RadarOnline.com readers know, the love birds have been caught showing off steamy PDA various times since beginning their May-December romance two years ago.
It all began in May 2017 when they were caught on a string of secret romantic dates.
The couple quickly shut down "showmance" rumors and attended the 2018 Met Gala together.
Not too long after, the couple — who have been very open about their 34-year age difference — announced the news of their engagement.
Foster, 69, proposed to McPhee, 35, during a luxury vacation to Capri, Italy.
“He did it at the top of this mountain in Anacapri. Totally dark, only stars,” the Scorpion wrote in a text exchange to a friend that she later posted on Instagram.
Despite being comfortable with their big age gap, she was bothered by how much it garnered the attention of critics.
“She was initially upset by the engagement,” a source told Radar. “It’s unacceptable, and she thinks he’s way too old for her.”
Foster’s daughter, Erin, however, instantly approved of her father’s decision to marry McPhee.
Under their engagement post, she commented “Mommmyyy” along with three red heart emojis.
Foster’s late father was allegedly also in support of their controversial relationship.
As readers know, Foster met McPhee in 2006 when he mentored her on American Idol. At the time, she was just 22, while he was 56!
In honor of McPhee and Foster’s upcoming nuptials, RadarOnline.com has compiled their steamiest PDA moments to date. Check out the gallery for more!
One year after her engagement, the Waitress actress will be walking down the aisle to become Mrs. Foster!
The composer, who has been married four times, is already a father to five, but has not yet ruled out having another child with McPhee!
Plenty Of Time
As Radar reported, when the UK’s Sunday Times asked of her having children, she responded “I have plenty of time.”
“We know lots of people who have big age differences with little kids and babies and they’re older than David and I are. You don’t hear about them much because they’re not celebrities,” she added.
McPhee and Foster have often been spotted on romantic dates — some which have included Foster’s adult children.
Recently, the duo attended the Carousel Of Hope Ball in aid of the Children’s Diabetes Foundation and the Barbara Davis Center for Childhood Diabetes.
Radar readers know McPhee’s friends surprised with a bachelorette party after one of her performances in London.
At her wild bash, a stripper dressed as a firefighter gave her a sexy lap dance.
The actress also went on a girls’ trip to Greece ahead of her nuptials.
She also jetted off to Italy with her hubby-to-be.
