The couple, who welcomed the baby girl in a New York City hospital on January 7, received a visit from Beyoncé's former Destiny's Child bandmate Rowland, who revealed that she couldn't stop staring at the little girl.
"She's absolutely beautiful! And I say that with such a huge grin! I'm so excited," Rowland told E! News.
Rowland also dismissed reports that she and fellow Destiny's Child singer Michelle Williams held a singsong for Blue Ivy when visiting, saying: "We all just stared at her. I just stared at her. She is so beautiful."
It was recently reported that Jay-Z threw an over-the-top party at his 40/40 club in New York City to celebrate Blue Ivy's birth.
Beyoncé and Jay-Z are apparently already considering schools to send their daughter to when she comes of age.
