Kelly Rowland Blown Away By Jay-Z/Beyoncé Preggers News

Former Destiny's Child member Kelly Rowland is the first of what will likely turn into many high-profile celebrities to react to news of her pal Beyoncé Knowles-Carter and Jay-Z expecting a second child together.

Shocked by the multipe anonymous confirmations, Rowland was speechless when approached by paparazzi following the news.

Former "Destiny's Child" singer Kelly Rowland had NO IDEA Beyonce was pregnant with a second child ... either that, or she deserves an Oscar for the performance she just gave in a L.A. parking lot. Kelly was on her way out of a cafe when we asked how she felt about the latest reports ... that Beyonce is pregnant with baby #2 -- and Kelly looked totally flabbergasted, saying, "WHAT?!?!" But it's likely she actually did know ... because as soon as we started asking more questions, Kelly clammed up. (TMZ)

While details are still fuzzy, multiple sources confirmed baby number two is on the way earlier in the day.

Blue Ivy's gonna be a big sis! That's right: Superstar supermom Beyoncé is expecting her second child with hubby Jay-Z, multiple sources exclusively confirm to E! News. The news follows rampant speculation that the "Countdown" songbird was pregnant, even as the couple remained tight-lipped about their ever-growing family. (E! Online)

The 31-year-old hitmaker had the Internet buzzing after nixing a concert earlier this week, which only sparked more pregnancy chatter.

Buzz of baby No. 2 on board kicked into gear on Monday. Now Beyoncé has announced she's canceling her Tuesday concert in Belgium because of dehydration and exhaustion. The singer's publicist tells AP that Beyoncé has been advised by her doctors to rest. She was scheduled to perform at the Sportpaleis in Antwerp. The show will be rescheduled and tickets can be used at that show. Her next tour date is Wednesday at the same arena. The statement says "she is awaiting word from her doctors before making a decision." (USA Today)

Prior to Blue Ivy Carter's birth last year, Rowland talked about her anticipation for Bey and Jay to become parents.

"I'm so happy for my sister and her husband. They're so happy in this moment right now, as they should be. They've made a little bundle of love, I'm so excited for them," she said in an interview. "I have no idea what I'm going to buy Beyonce at the baby shower because Jay is going to buy that little girl every single thing possible. She won't be spoilt but she will be very well looked-after. I'll be on hand for babysitting duties and I'm actually very good with messy diapers!" (Winnipeg Free Press)
