'"She's very smart. She's already reading flashcards. She's beautiful," Beyonce told chatshow host Oprah Winfrey.
The singer made these revelations about her intimate life, during her interview to promote her documentary "Life Is But A Dream", the Daily Mail reported.
Beyonce also opened up about the miscarriage she suffered prior to falling pregnant with Blue Ivy. "It was the saddest thing I've ever been through," she said.
Music megastar also talked to Oprah about the joys of becoming a mother for the first time.
She said, "It's what I'm most proud of and it just made everything make sense to me. I couldn't imagine my life if I did not have my daughter.
"I definitely want another child but it was also important for me to do what I love and I love to perform. I love to make music so I wanted to have my daughter. Maybe after the next tour I'll have another baby".
Beyonce even credits Blue Ivy with helping her complete her long-awaited documentary, which offers an intimate behind-the-scenes look at her relationship with rapper husband Jay-Z, as well as a look at the preparations for her performances.
