“We’ve known each other for less than a year now,” Nick explained. “The Bachelor Nation has a bit of a backlog with engaged couples, so there’s plenty [of] couples in line before us that have to tie the knot before we do.”

Holding off on making wedding plans wouldn’t raise suspicions if it were any other couple, but sources revealed exclusively to Life & Style that Nick and Vanessa’s relationship is on the rocks.

“Their relationship is super tense right now because Vanessa wants Nick to promote her and help her get attention and make more money,” the source explained. “She’s warned him that if he doesn’t do that, she’ll officially leave him and head back home to Montreal.”

Yikes — we wonder if Nick and Vanessa will ever make it down the aisle!
