Even Mariah's Dog Is A Diva! Carey Luxuriates In Bubble Bath - With Wine – And Canine!

At some point during Mariah Carey's storybook Valentine's Day with husband Nick Cannon, the American Idol diva took a relaxing bath with a glass of champagne…until the family dog dropped in to say hi, and RadarOnline.com has all the photos.

"Aaaah! Jill E Beans leaps to the tub In hopes of a splash champagne - whhhhhy?!" Mariah tweeted.

The show business power couple - parents to almost-2-year-old twins Moroccan and Monroe - spent a romantic day in New York City complete with horse-drawn carriages, red dresses and elaborate balloon creations.

"Trespassing in Central Park ❤ love on the wild side haaaaaa," she wrote, later tweeting, "A kiss delicately scented with horse dung.... Still romantic though.."

Fun fact: Prior to settling down with the America's Got Talent host, Mariah was romantically linked to baseball player Derek Jeter, and singers Trey Songz and Luis Miguel.
