Beyonce Knowles thinks Blue looks like Jay-Z

Beyonce Knowles thinks her baby Blue Ivy is changing all the time.

The 'Love On Top' hitmaker - who welcomed her first daughter on January 7 - has told singer Melanie Fiona, who is co-managed by Jay, she is confident the tot resembles her daddy but admits it changes every day.

Melanie told US Weekly magazine: "Beyonce says Blue changes every day and looks just like Jay now.

"She just is so happy. I've seen Bey like three times since she's had the baby. And she's just glowing and she's saying motherhood is the best, and she just loves it."

Discussing Jay, she added he was on a perpetual high.

She said: "He's in a good mood all the time!"

Beyonce's sister Solange Knowles recently revealed she would not be giving her sibling any advice about raising her daughter.

When asks if she gives advice, Solange said: "No, I really feel like because I had my son so young, I didn't want everyone's help. I think people felt entitled to give advice, so I'm always very sensitive to moms and letting them feel their way out. But there have been times when she'll ask, 'Did Julez do this? Did this ever happen with Julez?' And I'll gladly give her advice."
