McPhee, 34, and Foster, 68, first turned heads at a Grammy Museum event in September 2017.
Foster’s daughter, Erin, even jokingly called McPhee her “new step mom.”
Two months later, the two were spotted on a steamy date at an L.A. Lakers game, just days after Foster finalized his divorce from Hadid!
Things between the record executive and former American Idol contestant heated up quickly, as they were spotted all over each other just a few days later at a romantic restaurant in West Hollywood.
In December, the two were caught in a hot makeout session after a Beverly Hills lunch date.
As they welcomed in the new year together in Paris, things turned especially hot and heavy.
The two were all smiles – that is, when they paused long enough to separate their lips.
Even a simple trip to the grocery store is an opportunity for the love birds to share their passion.
