Justin Timberlake put on an impromptu show Wednesday at the wedding bash of Seventh Heaven actress Beverly Mitchell – as Jessica Biel looked on – Italian newspapers are reporting.

According to Il Foglio Costa di Amalfi, the pop star, 27, dance and sang with the mandolin and guitar players hired to entertain wedding guests in the Italian town of Ravello. Timberlake “appeared fun-loving and playful,” the paper reports.

Earlier in the day Wednesday, Biel, 26 – who was a bridesmaid at the wedding – was spotted emerging from the church clutching her bouquet of white roses while holding hands with Timberlake.

About 100 guests partied into the night in the gardens of the ancient Villa Cimbrone, which has breath taking views of the Amalfi Coast.

The couple preceded the wedding with a romantic tour of Italy. Most recently, they visited a vineyard inland from the Amalfi coast.

“Timberlake is a real wine connoisseur,” Gaetano Bove, the owner of the San Francesco di Chiara winery in the town of Tramonti, tells PEOPLE.

The winemaker said he took the two on a tour of his vineyard, followed by a tasting in he cellar. (Timberlake purchased a few cases of wine.)

He then invited the low-key pair to share lunch with the winery workers. They all happily noshed on pasta and potatoes with basil, bruschetta with tomatoes and roast pork on the patio.

Before he left, Timberlake played with the winery’s poodle and showed Bove pictures of his own dogs back in California. “He obviously misses them.”
