Looks like she may have already temporarily moved on, because she "recently connected" with Prince Harry's polo player buddy Nic Roldan while filming her new reality series in Florida.
Here's was a source had to say about it:
"Major sparks flew between Audrina and Nic Saturday night, and the entire evening they couldn't stop laughing and touching each other. Audrina seemed to be having the time of her life, dancing and mingling with guests, but you could tell she was especially focused on Nic."
AND it looks like they also met up the next day:
"He gave her a private polo lesson at the International Polo Club in Wellington."
Guess we'll see if this new guy sticks, or if she returns to Ryan Cabrera Corey once again.
