Cheers to the happy couple! Jason Aldean and Brittany Kerr toasted their engagement and upcoming wedding with a swanky party in Nashville, Tenn., on Saturday, Jan. 17 — and only Us Weekly has the exclusive pics from their celebration! 

Family and friends, including fellow country star Luke Bryan, who collaborated with Aldean and singer Eric Church on "The Only Way I Know," feted the bride and groom-to-be at the luxe Citizen Club, an exclusive venue for Nashville's elite.

Upon arrival at the secret location, the guests received champagne, as well as a special welcome from the "Burnin' It Down" singer, 37, and his future wife, who are set to marry later this year. Aldean looked the part in a black suit and white shirt, while Kerr turned heads in a beaded white frock.

Among the 100 or so attendees were Aldean's mother, Debbie Wood, his stepmom, Vivian Williams, and his sister, Kasi Morstad. Kerr's family, including mom Debi Kerr and grandmother Louvada Barbee, were also on hand to toast the lovebirds.

The elegant bash featured several personalized touches, including a photo booth and a custom-designed logo with the couple's initials set between a pair of antlers. The centerpiece was a six-tiered, white-frosted cake set atop a pedestal surrounded by candles.

The festivities went on well into the night, with partygoers dining and dancing until early Sunday morning.
