Beyonce shares handwritten apology for canceling concert

Beyonce wants her fans to know how sorry she is for canceling her concert on Tuesday in Antwerp, Belgium, on doctors' orders.

The singer's doctors had advised her to rest due to dehydration and exhaustion -- which did nothing to quell recent rumors that she may be expecting her second child with husband Jay-Z.

In a handwritten note posted on her website, Beyonce apologized for the canceled show and said she is now feeling better.

"To my dearest fans in Antwerp," the note began, "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."

Tuesday's show will be rescheduled and tickets can be used at the concert. Beyonce had already been scheduled to perform a second show in Antwerp on Wednesday. Based on her note, that concert appears to be going ahead as planned.

The 31-year-old launched her "Mrs. Carter World Tour" last month in Belgrade, Serbia. It wraps Aug. 5 at the Barclays Center in Brooklyn, N.Y.
