Those of you familiar with 'The Bachelor' probably remember that macadamia with "sparkle" and a whole lot of catfights, Tierra LiCausi, from Season 17. She fell in love with Sean Lowe pretty much immediately, then when she got booted from the 'Bachelor' mansion, she fell in love with someone else ... and promptly announced her engagement on the 'Women Tell All' reunion special.

Well, that "sparkle" wasn't enough to keep her sparkler, because her engagement is off. What happened?

Sources revealed to WetPaint that LiCausi's split with "the man who moved his entire life" to be with her isn't even a new one. "It's not a recent split," a source dished. "It happened a few months ago."

Which means they probably weren't together for that long, because 'The Bachelor' stopped filming in February 2013.

As for the mystery man, LiCausi's brother, Tyler, said that it was someone she was dating for three to four years before she was on 'The Bachelor,' and with whom she'd had a bad breakup just before the show began taping.

While LiCausi isn't the easy gal in the world to sympathize with, there's still a silver lining here: Perhaps a 'Bachelor Pad' appearance or new season of a love-to-hate edition of 'The Bachelorette' are in order.
