Beyoncé quashed rumors of marital discord Wednesday night when she dedicated the final song of her Miami concert to her husband, Jay Z, and their daughter, Blue Ivy.

“I wanna dedicate this song to my family,” the pop star, 34, announced to a crowd of 36,742 at Marlins Park stadium, where she kicked off her “Formation World Tour.” She added, “I wanna dedicate this song to my beautiful husband — I love you so much. Blue, I love you so much.”

Before launching into “Halo,” from her 2008 album, “I Am . . . Sasha Fierce,” she also gave a tribute to the late music star Prince, who died on April 21 at age 57, saying, “Prince, thank you for your beautiful music.”

Beyoncé released her album “Lemonade” over the weekend. The track “Sorry,” which features the lyrics “He only want me when I’m not on there / He better call Becky with the good hair,” prompted the rumors that Jay Z had been involved with another woman.
