Beyoncé Posts Handwritten Apology Letter to Fans for Canceling Show (READ)

Beyoncé posted a handwritten apology on her website to fans after she was forced to cancel her Antwerp, Belgium show on Tuesday. Under doctor's orders the "Diva" singer postponed the show due to dehydration and exhaustion.

Beyoncé's rep released a statement to the Associated Press, saying doctor's advised the singer she needed to rest. Beyoncé is scheduled to perform another show in Antwerp but is "awaiting word from her doctors before making a decision" on Wednesday night's show.

The canceled show will be rescheduled and the already purchased tickets can be used at that show.

In the apology letter, Beyoncé told fans how hard it was for her to make that decision and she has never postponed a show in her life. She also thanked fans for their concern and assured them she was fine.

The Mrs. Carter Show world tour began April 15 in Serbia and is scheduled to continue through Aug. 5 where she will perform at the Barclays Center in Brooklyn. The cancelation comes just days after speculation that the singer was pregnant with her second child.

Pregnancy rumors began after a photo surfaced on blogs that showed the singer during a recent concert with what people are assuming is a baby bump.

Beyoncé told "Good Morning America" London that her and husband Jay-Z wanted their daughter, Blue Ivy, to become a big sister. She did not say when they plan on expanding their family.

Entertainment blog Media Takeout reported that the pregnancy rumors are true and they received confirmation from a "quasi-official" member of Beyoncé's team. The blog said the insider shared with them that the singer wants to keep the pregnancy secret until she was out of her first trimester.
