Adam Levine will have one of his Maroon 5 bandmates by his side when he marries Victoria's Secret model Behati Prinsloo this weekend. According to Maroon 5 guitarist James Valentine, Levine has asked the band's keyboardist Jesse Carmichael to be his best man.

"Those guys go back," Valentine told 2DayFM ahead of the nuptials. "What's interesting about the band is, I've been with the band for 15 years but I'm still one of the 'new' members!'"

Carmichael recently rejoined Maroon 5 after going on hiatus from the band when they released "Overexposed" in 2012.

Valentine will however play a role in Levine's big day. He will play a "nice little medley" of Beatles tunes, he added. "I'm gonna be playing some solo acoustic guitar during the ceremony when people are walking [in]."

The wedding will reportedly take place on Saturday, July 19. Access Hollywood further reports Levine and his blushing bride will walk down the aisle in Cabo San Lucas, Mexico. In addition to his Maroon 5 bandmates, the site reports that Victoria's Secret models Candice Swanepoel and Erin Heatherton will be in attendance. Jonah Hill will also be there; his brother Jordan manages Maroon 5.

As for the groom, he is feeling rather relaxed with only a little bit of time left as a bachelor. Valentine told ABC News Radio. "I think he's really excited. I expected him to be more nervous. They're very amped up. They're very happy. It's going to be really fun."

Levine's wedding comes just months before Maroon 5 will drop their new album, "V," on Sept. 2.

"A lot of our fans would love to hear us make another 'Songs About Jane' type of record, and I think as some point we'll go back in and make a record in that sort of way, but this is not that type of record," Valentine told Billboard about the new album. "I think it's a natural evolution for us. The sounds that we're interested in right now are coming from lots of different arenas, lots of different worlds. It's not the way we used to make records. And it's about wanting to be part of the dialogue of what's happening on radio right now and being a part of that. It's more of a producer's medium right now. So right now it's about experimenting with more of these electronic elements and more of the beats and seeing where that takes us. That seems more exciting right now."
