Audrina Patridge has split from her boyfriend.

The reality TV star and Australian BMX rider Corey Bohan have split for good after five years of dating and though they have parted ways previously, insiders don't believe they will reconcile this time.

A source told Us Weekly magazine: ''She's single right now. I don't think they'll get back together this time.''

The pair most recently split in March 2011, and Audrina, 29, said last summer they were stronger than ever and even ''talked about'' marriage.

She added: ''We've been off and on for almost five years but we've been solid.''

While it is unclear when the couple split, they were last seen together enjoying a vacation in Mexico in May, and seemed very close and affectionate with one another.

However, the former 'Hills' star posted a number of cryptic messages on her Twitter account over the weekend.

One, a quote by Andre Malraux, read: ''Man is not what he thinks he is, he is what he hides.''

And another said: '''You can't start the next chapter in your life , if you keep re-reading the last one' #future #dreams #followyourheart (sic)''
