"This was a dancing crowd," says a guest who attended the July 19 festivities at Flora Farms in Los Cabos, Mexico, where the bridesmaids wore different cream-colored dresses by Rory Beca. "Everyone was dancing late into the night."
According to another wedding guest, at one point Levine, 35, and Nicks sang a duet as his Maroon 5 bandmates joined them on stage. Even the bride joined in on the fun, singing the Bright Eyes song "First Day of My Life" and dedicating it to her groom.
"Everyone cheered for her," a guest says.
In between music sets, there were several speeches that "had guests laughing," a source says.
At the reception, said to be designed and coordinated by wedding planners Yifat Oren and Stefanie Cove, guests sat at large circular tables around big mango trees. Long garlands of flowers provided by Arete Florals and tiny white lights that looked like fireflies hung from the trees.
Guests dined on organic pork chops, fresh fish and beet salads, and later, for dessert, indulged in alcohol-infused paletas (Mexican popsicles) and treats from an organic ice cream cart. "Most people finished eating in under an hour and were ready to party," a source says.
"Everyone was having so much fun," a guest adds. "Adam and Behati didn't stop smiling the entire night."
