Not quite!  While there’s been much speculation over when 19-year-old Miley Cyrus will tie the knot with her longtime boyfriend, Liam Hemsworth, 22, the former Disney star assures everyone that she won’t be walking down the aisle any time soon.

“We want to have a long engagement,” Miley tells the September issue of Marie Claire.  "I don't really care about the wedding or the piece of paper as much as I do the promise we've made to each other."

She adds,  “Life is too short not to be with the person you want to be with.”

The young couple -- who met in 2009 when they co-starred in The Last Song — announced their engagement in early June after photos of the actress wearing a gorgeous 3.5-carat with 18-karat gold Neil Lane sparkler on her ring finger surfaced.

"I had no input," she says about the picking of the ring, which was hand-cut in the late 1800s. "I saw it online at one point and thought it was really pretty. I just love that it's old and has a story. And I'm happy because it doesn't look like anything else I wear."
