Beyonce Apologizes For Canceled Show, Will Hit The Stage In Belgium Tonight

Queen Bey's back at it!

Beyonce is ready to take Belgium by storm tonight after cancelling yesterday's concert in the same Antwerp venue due to "exhaustion and dehydration."

She took to Facebook to apologize and confirm that she's back in action for her Mrs. Carter World Tour. The show she missed will be postponed and the tickets will be refunded.

"To my dearest fans in Antwerp. I've never postponed a show in my life," she hand wrote. "It was very hard for me. I promise I will make it up very son. I'm sorry if I disappointed you."

According to her publicist's statement, the Grammy winner was advised by her doctors to rest yesterday in lieu of performing. "Thank you for your concern," the songstress wrote. "I'm feeling much better now, and I'm ready to give you a great show. See you tonight. All my love, Beyonce."

The incident only added fuel to the fire. The "Love on Top" singer is rumored to be expecting her second child with husband Jay-Z after photos surfaced of her sporting what seemed to be a small baby bump during a performance.

A source close to Beyonce told Us Weekly that she's not expecting. "She was genuinely sick from pushing herself too hard like she always does," the source said. "The show is very strenuous. ... These rumors come out every month!
