I'm pissed with Rihanna

She rescheduled her date in Dallas from 3/6 to 5/13! The REAL prob is I will be 19weeks instead of 9! I'm so freakin irritated! And it was gonna be my nieces first concert! What 19 yr old wants to go with a pregnant auntie... Idk, maybe I'm just being negative but that just sucks
