Actress/singer Katharine Mcphee's estranged husband Nick Cokas has filed new divorce documents challenging her version of the split.

The Smash star hit headlines last year (13) when she was pictured kissing married Tv director Michael Morris. At the time, it was reported she had been separated from actor/producer Cokas for some time before the scandal.

The couple, wed since 2008, sparked rumours of a reconciliation in March (14) when they were spotted together in public but MCPhee subsequently issued divorce papers in May (14).

Cokas has now filed documents of his own to contest the date of separation MCPhee gave. The actress claims they split in March, 2013, months before her brief fling, but Cokas alleges they were still together at the time.

In legal papers obtained by Tmz.com, Cokas claims he has evidence to prove they received marriage counselling after the pictures surfaced.

The separation date is essential in deciding how their money will be shared. Cokas is also seeking spousal support.
