The Jersey Shore star, 35, and O'Day, 32, have split, according to E! Online.
The pair met while filming the new reality show Famously Single, and a source told PEOPLE in February that they were "definitely dating.
At the time, the source said they were "still testing it out" and that the relationship was "nothing serious.
Now, O'Day tells E! it was absolutely serious.
"I'm the first girl Pauly has ever loved as he admits on the show – never loving before me," she said. "He brought me into his life with his daughter and mother, who I respect dearly. Nothing about our relationship was not serious. Neither of our busy schedules have anything to do with why this didn't work. At the end of the day, we tried our best."
