TV presenter Donna Air has split from her partner of six years, zoo owner Damian Aspinall, because of the tycoon�s reluctance to marry.

The 27-year-old Newcastle-born TV star has revealed to friends that she is moving out of the �15m wildlife park in Kent that Damian inherited from his father John in 2000.

"Donna wanted to get married and Damian didn't," a friend tells The Daily Mail. "He also wanted to have more children but Donna wasn't ready.

�She's a great mother, but also a career girl. They have decided to separate but no one else is involved."

The couple has a three-year-old daughter, Freya, together.
