Beyonce Knowles is getting closer to marrying longtime boyfriend Jay-Z, after confessing that her sister Solange has made her think seriously about turning her back on single life.

The former DESTINY'S CHILD star tells the new US issue of Cosmopolitan that she has become a big fan of marriage after watching how happy her 19-year-old sister is since exchanging vows and starting a family.

She says, "I don't know when I'll want to get married. I never pictured myself as a bride, but, after my sister's wedding, I did start thinking about what kind of wedding I'd want. I don't think I want a big one."

Knowles admits she's already thinking about her bridesmaids - she tells the magazine that her former bandmates Kelly Rowland and Michelle Williams will join her at the altar.

While the singer might be seriously considering getting married, she's not sure she wants kids just yet.

She adds, "I didn't want to be in the delivery room (for Solange's birth)... but I was moved by the experience, so it didn't make me not want to have kids.

"I babysat for my nephew last week and it's not as glamorous as it looks."
