"Just So You Know" ladies, Jesse McCartney has truly found a "Beautiful Soul" in his longtime girlfriend Katie Peterson and as much as we hate to break it to you, the two are set to tie the knot soon!

The singer-songwriter happily announced last September 14 that he's marrying his girlfriend of seven years. "Locked it up," Jesse wrote.

Katie also posted on her Instagram with the caption: "SEVEN YEARS.. and also forever."

Reports say Jesse proposed to Katie last Friday at a restaurant in Los Angeles. And while some fans are delighted for the singer, others are clearly devastated. Check out some of the hilarious reactions below:
