She may be going through a nasty divorce but Kelly Rutherford is still seeing the silver lining.

"He gets up in the morning and he gives her a kiss and he goes ‘tickle, tickle!,' " said Rutherford. "He talks about her and
how she can't eat yet, and he's so lucky he can have ice cream, and he can't wait to introduce her to [to it]. It's really cute.”
