The American Idol judge's dog joined her in the bathtub Thursday!
Hilariously, Mariah tweeted a picture of herself and the pup in the tub, writing, "Aaaah! Jill E Beans leaps to the tub In hopes of a splash champagne - whhhhhy?!"
The mom of two then proceeded to livetweet her and Nick's V-Day celebrations, which included receiving "I Love You" balloons and taking a horse-drawn carriage ride through NYC's Central Park.
She even tweeted a shot of her and Nick making out in the carriage, quipping, "A kiss delicately scented with horse dung.... Still romantic though.."
Oh, Mariah, never change!
