Actress and Tv personality Ricki Lake's estranged husband has asked a U.S. judge to dismiss their pre-nuptial agreement amid allegations his estranged wife tricked him into signing the financial contract prior to their wedding in 2012.

Lake filed to end her marriage to Christian Evans last month (Oct14), citing irreconcilable differences.

She offered to pay Evans spousal support in the divorce, but the proceedings are on the verge of turning nasty after the jewellery designer filed legal papers seeking the invalidation of their pre-marriage contract.

In documents obtained by Tmz.com, Evans claims his ex committed fraud in convincing him to agree to the pre-nup, which specifies the amount of his spousal support payments, but he fails to go into further details about the allegation.

If his request is granted, Evans will be entitled to half of all of Lake's earnings during their marriage.

The divorce is Lake's second - the one-time talk show host ended her 10-year union to artist Rob Sussman in 2003.
