(IDEX Online) - Romantic William Hunn bought five engagement rings for his girlfriend - so she could have a choice when he made his surprise proposal. He took Brittney Miller on a helicopter ride around Atlanta, Georgia, USA, before dropping to one knee and asking her to marry him."You can try all five or pick one," he told her, in a video he posted to Instagram (see pic).He'd joked with his jeweler about proposing with five rings, then realized it was perfectly possible. After Brittney settled on her favorite - a custom-designed rectangular-cut diamond ring - William sold the rest back at a reduced price.The couple first met 10 years ago at Clarke Atlanta University, were good friends, and began dating a year ago.
