Things have not always been smooth between two of the world's biggest pop stars.
Even though singers Pink and Christina Aguilera were working together for the song 'Lady Marmalade' in 2001, the two have had some rough "history".
"Her and I have had history and it hasn't always been wonderful," Pink told TV show Entertainment Tonight. "I think it just took us 15 years and I feel like there was true love and it felt really good."
The two are back working together on The Voice, where Pink will appear as a guest mentor.
"I love when you're around long enough to have a full circle moment and that was a full circle moment for me because in all honesty, I'm a fan of hers," the 36-year-old said. "It was just a really refreshing, nice visit."
