Solange Knowles, Alan Ferguson Pregnant: Beyonce's Baby Sis Having Baby Number 2!

Singer Solange Knowles is allegedly pregnant with her second child with fiancé, Alan Ferguson.

A photo obtained by MediaTakeOut.com, shows the glowing singer with a visible baby bump. In 2004, Beyoncé's sister gave birth to her first son, Daniel Julez J. Smith, Jr. after marrying her teenage sweetheart Daniel Smith.

In June, the singer reportedly got engaged to her boyfriend of 5 years, Alan.

The starlet reportedly celebrated her 28^th birthday Tuesday with an engagement ring from her 51-year-old boyfriend, according to MediaTakeOut.com.

In an interview with NecoleBitchie.com, the "Sol-Angel" singer revealed that she made the first move when she saw Alan, "Certainly, in the beginning I was the one who approached him so I have always sort of historically been one of those girls that goes after something that I'm into," she said. "I'm not very old school and like, I'm gonna wait on you. Wait for you to approach me type of situation. I have a lot of guy-like quintessential relationship qualities that I have had to work on."
