Jenny McCarthy has split from Brian Urlacher.

The 39-year-old model has vowed to enjoy an ''amazing Friendship'' with the Chicago Bears linebacker after ending their four-month romance.

She told People: ''Brian and I have decided to turn our romance into an amazing Friendship.

''I will continue to be the biggest cheerleader for him. Go, Bears!''

Jenny recently moved back to her native Chicago with her nine-year-old son Evan and admitted her romance with Brian was one of the factors in her decision.

She said: ''I'm from there and I feel like my son is not getting the childhood that I wanted in LA.

''On top of that, I met someone I like and care about, so all those things combined takes me back home.''

However, she admitted Evan - who suffers from autism - wasn't impressed by Brian's sporting fame.

She added: ''My son doesn't watch football. He judges people on their spirit, which is perfect.

''The relationship is still new, but my son loves being back in Chicago with his friends. His happiness is the most important thing to me - and my mom and dad live there - so, we'll see how the relationship develops.''
