Former 'Hills' star Audrina Patridge has called it quits with Corey Bohan, her on-and-off again boyfriend of five years.

According to an Us Weekly source, the former reality star is "single right now," adding that unlike after their previous splits, "I don't think they'll get back together this time."

While it's unclear what caused a rift between the two, Patridge's Instagram may offer some insight, as she recently posted a cryptic quote that reads, "Man is not what he thinks he is, he is what he hides." The same day, she posted the following message on Twitter:

Patridge and BMX biker Bohan first began dating in 2009, and despite some breakups along the way, seemed to be going strong after their most recent split in 2011. In July 2013, the model gushed to Us that Bohan was "the love of her life," though she acknowledged that their long distance relationship made things difficult.

Heartache or not, Patridge still looked as radiant as ever at the 2014 Young Hollywood Awards over the weekend, which she was psyched to attend.

In addition to Bohan, Patridge also dated Justin Bobby Brescia from 'The Hills,' Ryan Cabrera and Chris Pine.
