On Saturday, the night before their Palm Beach, Florida, wedding, the pair had a pre-wedding celebration with their friends and family at a cocktail and desserts party at the Breakers Resort after their rehearsal dinner.

A party guest shared an adorable video on Instagram from the party, featuring Manganiello serenading his bride-to-be with Guns N' Roses' Sweet Child O' Mine and taking advantage of an instrumental break to plant a kiss on Vergara's lips.

Another guest shared several videos of Vergara, in her custom-made, pearl-pink party dress, dancing and singing along to the musical stylings of Jorge Celedon.

Vergara, 43, also posted plenty of pics from the night's festivities on her own Instagram, including one of her dancing onstage in her sparkly dress and another of her and Manganiello, 38, going in for the kiss.

The couple have been together for almost a year and a half. The Magic Mike XXL star proposed to Vergara last Christmas during a romantic vacation in Hawaii.
