The U.S. reality TV hunk who is dating Donald Trump's ex-wife Marla Maples is preparing to ship out for active duty in the Middle East. Navy doctor Andy Baldwin, who set hearts racing as The Bachelor on the show's 10th season last year (07), is scheduled to spend the next few months in the Middle East before returning to his base in Hawaii in March (08), according to U.S. publication In Touch Weekly. Friends tell the magazine that Maples, the mother of Trump's daughter Tiffany, has promised Baldwin that she will "wait for him" until his tour of duty is over. A pal says, "They have great chemistry. It could lead to marriage."
