P!nk sings tribute to Sinéad O’Connor with Brandi Carlile at Cincinnati concert

Grammy-winning artist P!nk paid a special tribute to Irish singer-songwriter Sinéad O’Connor at Wednesday night's concert at Great American Ball Park.

O'Connor died Wednesday at the age of 56, according to a statement from her family. The cause of her death has not yet been disclosed.

P!nk brought opener and Grammy-winning Brandi Carlile back onstage for a performance of O'Connor's hit "Nothing Compares 2 U." The two sang an emotional duet of the song originally written by Prince, backed by a grand piano.

"Can't think of two mightier women to honor her," one Twitter user wrote.

O'Connor rose to stardom in 1990 after her sophomore album "I Do Not Want What I Haven't Got," which included her cover of the Prince song that P!nk and Carlile performed Wednesday night.

Her death comes over a year after the death of her 17-year-old son, Shane, who died by suicide. O'Connor reportedly posted on social media a myriad of now-deleted tweets, saying she was "ruined" without her son.

P!nk's Summer Carnival Tour continues July 31 in Boston.
