Sofia Vergara is getting married to Joe Manganiello today in Palm Beach, Florida. Saturday night found the entire wedding party gathered for a rehearsal dinner and celebration.

Part of that celebration turned incredibly sweet when Manganiello serenaded his bride-to-be. The Magic Mike XXL star sang “Sweet Child of Mine” to Sofia Vergara.

A source tells Us Weekly of the obvious love between Sofia Vergara and Joe Manganiello on the night before their wedding.

“As he sang, Sofia threw her arms up in the air and screamed as she approached the stage,” the source says. “Joe crouched down to meet her gaze and said, ‘Te amo,’ into the microphone. Sofia grabbed his neck and they kissed a dozen times. Then Joe jumped off the stage and they continued kissing and embraced.”

Several of Sofia Vergara’s Modern Family costars were in attendance at the night-before festivities. Julie Bowen, Sarah Hyland, Dominic Sherwood, Eric Stonestreet, and Jesse Tyler Ferguson celebrated along with Sofia and Joe on their last evening as singles.

Joe Manganiello’s Magic Mike XXL costar Channing Tatum was there with wife Jenna Dewan, too.

Sofia Vergara was a stunning bride-to-be, wearing a form fitting white lace and mesh tea-length dress to the rehearsal dinner and party. Joe Manganiello wore a black tux. Guests had a fun evening, dancing to Latin music until the wee hours. Nothing quite compared, however, to that moment when Joe serenaded Sofia Vergara in front of the entire crowd.

Capping off the romantic evening, Sofia Vergara shared an Instagram shot she captioned very simply.

“Goodnight,” it reads.
