Beyonce's dad reveals he had no idea singer was pregnant until Instagram news

Beyoncé didn't tell her dad she was expecting twins. The superstar singer revealed on her Instagram account on Wednesday that she and husband Jay Z are expecting twins and the news came as much of a shock to her father Mathew Knowles as it did her fans.

Mathew, who teaches entertainment industry courses at Texas Southern University, explained on The Insider:

"I was shocked. Let me tell you what happened. I got a first text, and I was like, 'Why is this person saying congratulations?'

"Then I get a second text from one of my students at Texas Southern, and I was like, 'What are you talking about?' He was like, 'Go to the web.' I didn't know myself."

However, once he heard the news, Mathew who used to be Beyoncé's manager quickly called his daughter and they had a "wonderful" chat.

He said: "I was like 'B,' [and] she said, 'Hi, Dad.' I was like, 'You're OK?' Because she sounded a little tired because she's working on the Grammy performance.

"Beyoncé and I had a great conversation. I'm looking forward to seeing her soon and I told her, 'Look, slow down a little bit. You need to slow down a little bit.' "

While he was kept in the dark about his daughter's happy news, the patriarch thinks the way the Crazy in Love singer made her announcement was "smart".
