"We're sort of in the preliminary stages," Davis told ET at the SI Swimsuit 2016 launch event in New York on Tuesday. "I don't know if I'll give too many details before the actual day, but I'm very excited that she's designing the dress."

The 41-year-old former Yankees shortstop and the 25-year-old beauty announced their engagement in October, after being linked since 2012. The following month, Davis was spotted out in New York with a diamond sparkler valued at close to $300,000.
