We've been so thrilled since we found out Big Time Rush's Carlos Pena proposed to girlfriend Alexa Vega, but what makes us even more excited is finding out James Maslow, Kendall Schmidt, and Logan Henderson were all part of the master plan!

In J-14's EXCLUSIVE interview with the BTR guys, we got the scoop on exactly what went down with Carlos' proposal. It turns out the guys had known about the proposal for three months before it actually happened and Alexa was totally clueless! They're sure good at keeping secrets.

"[I proposed] at a big dinner. The boys and I went on a cruise and we had a big dinner the very first night," Carlos told J-14. "Logan helped me out, James gave me some courage, and Kendall brought the tears."

He also told us there were some criers during the proposal, and one of them may shock you! When we asked if Alexa cried, Carlos said, "Yeah, and so did Kendall."

Kendall chimed in, saying, "It's emotional! I had never been around an engagement before, and especially not one that was as cute and sweet as the way he was doing it."

Are you happy the BTR guys were included in Carlos' proposal? Let us know in the comments!
