Country singer and current Biggest Loser contestant Vinny Hickerson is engaged, reports People. Hickerson, half of country outfit Trailer Choir, planned a surprise proposal at the Grand Ole Opry for long-time girlfriend Lori Diaz. Hickerson chose the iconic performance venue because “it’s a place where so many dreams have come true…. My biggest dream is to be a great husband and a great father, and fall in love.”

While cameras filmed the big moment for tonight’s episode of The Biggest Loser, Hickerson dropped to one knee and presented his girlfriend with a ring evoking the romantic Eiffel Tower. They celebrated their ‘yes’ moment with a private concert by country stars Thompson Square. “I’ll never forget that night for as long as I live,” gushed Diaz. “It was so perfect, even more perfect than if I had planned it myself!”

Hickerson signed on for Biggest Loser to set a good example for his future stepson, Diaz’s 9-year-old son Brennon, and has lost 112 pounds so far.
