Don’t try reaching Miss Alabama Katherine Webb by phone. We’re told AJ McCarron’s girlfriend — who caused a media storm when ESPN’s Brent Musburger focused his flattery on her during Monday’s game — has changed digits. “She was forced to change her phone number,” Donald Trump told us at Trump Tower during an event for Miss Universe. “She was getting thousands and thousands of calls. Katherine has to stay grounded now that she’s become a big star.”
