The reality TV star recently reconciled with the singer following her separation from husband Corey Bohan, the father of her two-year-old daughter Kirra, a year ago (Sep17).
In May, Audrina and Ryan, who split in 2010, jetted off to Los Cabos for Patridge's birthday and the following month Audrina opened up about the relationship with the singer, insisting things couldn't be better.
"I'm the happiest I've ever been right now," she told People magazine. "You know, things are going really good."
"We're just having fun. Nothing is forced," she continued. "You know, great things happen when it's not forced, and things are naturally just happening. And that's what it is. We just have the best time together."
However, according to the magazine, the couple has split.
Audrina and Ryan appeared to go public with their reunion in late April, when they attended California's Stagecoach Festival together. The outing came a month after Audrina filed court papers seeking to strip Bohan of his visitation rights, accusing her ex of displayed "angry, rude and emotionally abusive" behavior toward Kirra, while trying to keep tabs on his former partner's whereabouts.
Corey has denied the allegations and the former spouses' divorce proceedings remain contentious. Earlier this month, Corey was fined $1,000 (GBP760) for failing to turn over documents relevant to the custody battle. Patridge was seeking documentation of conversations between the two of them and additional financial information.
