Girardi's comment came after the reality star and musician spoke of the issue on the show, claiming that despite Vanderpump's claim on the color, she would continue to wear pink whenever she pleased.

After seeing what her co-star had said, Lisa Vanderpump responded to Giradi with a tweet of her own.

"It belongs to me, I bought it years ago," Vanderpump wrote to the singer, explaining, "It lives in my house, blooms in my garden and fills my closet."
