Mindy McCready welcomed son Zayne this week, People reports. While reports earlier this year said that the country singer was having twins, just one baby arrived on Monday. “At the time of the initial announcement surrounding Mindy’s pregnancy, in consideration of her size, Mindy was certain she was carrying twins; a misinterpreted sonogram seemed to support her feelings and excitement,” McCready’s rep told E! News. Zayne is her first child with boyfriend David Wilson; she has another son, Zander, with ex Billy McKnight.
