Selena Gomez, 19, cancelled two concert dates after she found out her mother, Mandy, 35, reportedly suffered a miscarriage. The singer/actress learned the news last Friday and immediately cancelled concerts that were to take place Saturday in Chicago and Sunday in Seattle. Selena posted on Twitter last month that her mother was expecting a child with her husband, Gomez’s stepfather Brian Teefey. Both Selena and her boyfriend, Justin Bieber, were seen visiting Mandy in the hospital. The Wizards of Waverly Place star will still perform at MTV’s New Year’s Eve party, co-hosted by fellow former Disney star Demi Lovato and Teen Wolf star Tyler Posey at MTV’s Times Square studio. At the same time, Bieber will be performing as part of Dick Clark’s New Year’s Rocking Eve in Times Square.
