Ha! A bikini-clad Audrina Patridge got dunk into a tank filled with water on Wednesday’s Ellen.

Audrina also dished to a concerned El about the recent rumors that on-again/off-again BFF Lauren Conrad has been hitting the sheets with her ex-boyfriend, Justin Bobby.

“After I found these rumors out, she chose to talk to me through the tabloids and not come directly to me or call me, as a true friend. Neither of them have really talked to me or made an effort, so I really don’t know what to believe. I don’t want to believe it.”

“She hung up on me and that was my way of making an effort and asking her,” Patridge says of Conrad. “I never accused anyone. I just straight-out asked them if they did it or not, and I don’t know what to believe.”
