The site also mentioned that the two shared a splendid evening at El Dorado in Los Cabos, Mexico on Friday night. There was a big party on the beach that consisted of about 100 guests who casually dressed up and had drinks at a large bar, according to a source.

The evening appeared to dazzle with more romance with tables covered with red flowers. Once it got closer to the night, candles and sparkling lights apparently started glowing as well.

Two celebrity guests included two movie star comedians Jonah Hill and Jason Segel along with some models who attended.

"Everyone is very excited about this marriage," the source said. "They are a wonderful couple."

According to a report from ABC News, Maroon 5 guitarist James Valentine mentioned that keyboard player Jesse Carmichael is going to be Levine's best man. Valentine also mentioned that the lead singer is looking forward to his big day.

"I think he's really excited," the guitarist said. "I expected him to be more nervous. They're very amped up. They're very happy. It's going to be really fun."
