Katharine McPhee is a bride-to-be!
Hours ago, the American Idol runner-up confirmed that music mogul David Foster had proposed after more than a year of dating. McPhee shared a text conversation with a friend on Instagram, revealing that Foster popped the question on a mountain in Capri, Italy during a moonlight stroll.
And while she's yet to unveil what it's expected to be one incredible diamond bauble, an insider describes the engagement ring as "very elegant and large."
"They are both very happy and over-the moon-excited," adds the source. "Katharine has been wanting this for a while now. David has been planning the engagement, but has kept it very secretive. Only a few family members knew about his plans."
The future newlyweds have known each for more than a decade, but only recently did Katharine and David find themselves single at the same time and ready to embark on a new relationship. McPhee, 34, was previously married to Nick Cokas for six years, while Foster, 68, has been married four times.

The "Over It" songstress plays coy about the dynamics of their relationship in a 2017 interview with Health magazine, sharing, "We're very close friends, and we've been friends for a long time.
