(Cover) - EN Showbiz - Jim Carrey and Jenny McCarthy split because they stopped having fun together.

The couple called time on their romance in April, after five years together. They made sure the split was amicable, and Jenny has now spoken about it publicly for the first time. She explained there was no big thing that drove her and Jim apart, rather that the romance just stopped working.

You know, the simple word I can give and there's a few, so let me say a few. The first thing is, when it's not fun anymore, you need to start investigating and do an inquiry into the relationship, she explained.

Jenny also discussed the way she was perceived while dating Jim. The 37-year-old former Playboy model insisted she wasnt impressed with the 48-year-old actors star status, although many thought she was. Jenny says she went to great lengths to ensure she didnt get taken in by the fame game, especially as she knows it would have a damaging effect on her eight-year-old son Evan, her child with ex-husband John Mallory Asher.

I've learned that, and this is why my identification wasn't caught up [in] being a celebrity's girlfriend, she told American talk show host Oprah Winfrey, in an episode airing today. It wasn't at all. Absolutely. I did check on that, by the way. I checked into myself. How does my ego feel? My ego's fine. I'm a warrior mom. I always got back on my feet, and I know especially this year who I am. (C) Cover Media
