Adam Levine and Behati Prinsloo are planning to tie the knot this coming summer. Sources close to the couple told Us Weekly that the duo will wed in Cabo San Lucas, Mexico and later travel to Prinsloo's native South Africa to "celebrate with people who can't make the trip." "The Voice" coach and Maroon 5 front man got engaged to the Victoria's Secret model, 25, last July. The two began dating in 2012 and broke up in the spring of 2013 before they reconciled and decided to get married. Levine said, "[Prinsloo] makes me the best person I can be" while speaking to reporters at the Tribeca Film Festival screening of his upcoming movie "Begin Again" in late April.
