Jenny McCarthy has announced that her and her boyfriend of four month Jason Toohey are splitting up.

In Touch have revealed that Jenny, who started dating the Las Vegas body builder soon after her surprise split from Jim Carrey broke the relationship off after the American Music Awards on November 21.

"He couldn't handle her fame and the amount of attention she received, so she ended it," an insider explains. A rep for the 38-year-old model mom tells In Touch,

"They are on good terms and will remain friends."

Jenny and funny man Jim Carrey announced their split on Twitter in April after spending five years together.

In an interview with Oprah in September the blond actress said she just knew the relationship was over.

“You know, the simple word I can give — and there’s a few — but the first thing is when it’s not fun anymore you need to start investigating and do an inquiry into the relationship,” Jenny explained.
