America's Next Top Model alum Eva Marcille and House of Payne actor Lance Gross are engaged, reports Essence.com. Gross proposed with a 3.36-carat diamond engagement ring by Cartier on Christmas Eve while vacationing at the Big Bear ski resort in the San Bernardino Mountains."I was in a complete state of shock!" Marcille says. "I could not even sleep because I was afraid that I might wake up from the most beautiful dream ever." The couple, who have been dating for a year and a half, haven't announced any wedding details.
