Pivarnick announced her pregnancy on Wednesday (27Apr11), but it appears she'll be a single mum - Dave Kovacs has dumped the reality TV star after learning she had been unfaithful with a fireman.
He says, "I'm going through a really tough time right now. I have ended things with Angelina. I got a text from a firefighter who actually apologised for sleeping with Angelina saying he just found out she was engaged. I actually found a pair of guy's underwear in her car.
"I truly fell in love with this girl and wanted to have a family and grow old with her."
Kovacs proposed to the Jersey Shore star in February (11).
