The former lingerie model, 34, wed billionaire Evan, 26, in a backyard ceremony at their Brentwood, California estate in front of around 40 guests, and as they celebrated their nuptials, the bride reportedly stepped up to the microphone to sing to her beau.
In audio footage obtained by TMZ.com, a female voice, believed to be that of Miranda, can be heard performing a karaoke version of Shania's 1997 hit, much to the crowd's delight.
The couple met in 2014 and announced their engagement last July after 13 months of dating.
It was Miranda's second trip down the aisle. She was previously married to British actor Orlando Bloom, the father of her six-year-old son Flynn, from 2010 to 2013.
The former couple has remained close since ending its romantic relationship, and Orlando was even pictured spending time with Flynn and his former father-in-law John Kerr in California on the eve of Miranda's big day.
It's not known if the Pirates of the Caribbean star was among the guests invited to his ex-wife's wedding.
"We're a modern family," she told People. "Orlando and I are literally like family, he's like a brother to me. It's very weird, but we really care for each other and we have a great relationship, so I feel very lucky."
