Beyonce baby rumors were being reported by media outlets last Friday saying that the singer is expecting her second child.

However, the singer took to Instagram this weekend to play down the rumors, writing: "I can't stop the rumors from starting, and I can't really change people's minds who believe them, all I can do is sit back and laugh at these low life people who have nothing better to do than talk about me." But the message was quickly deleted after it was posted.

She defied the pregnancy rumors by donning tight fitting costumes at her concert in Milan. The 31-year-old is currently on her Mrs. Carter Show world tour and the latest pregnancy rumors were sparked when she suddenly canceled one of her concerts at a doctor's request.

Beyonce had canceled a concert in Belgium on May 14 after reportedly being "advised by her doctors to rest as a result of dehydration and exhaustion." The concert was rescheduled the following day, in which a photo of her in a blue sequined costume showing a rather rounded belly had leaked, fuelling the pregnancy rumors.

Beyonce had written a handwritten apology to her fans for canceling her show, which was her first concert cancellation. She posted a photo of the note on her Facebook: "To my dearest fans in Antwerp. I've never postponed a show in my life. It was very hard for me. I promise I will make it up very soon. I'm sorry if I disappointed you. Thank you for your concern. I'm feeling much better now and I'm ready to give you a great show."
