While the divorce was thought to be quick in light of the pre-nuptial agreement the couple signed prior to their wedding on Dec. 31, 2013, Sweeting's recent filings suggest the process might take longer than expected.

Cuoco cited "irreconcilable differences" as the reason for the breakup in her divorce filing, which a source close to Sweeting told ET "was a long time coming."

In Sweeting's response, he lists the date of separation as Sept. 25, 2015 -- the day the split was announced -- which is three weeks later than the date Cuoco listed as their separation date in her divorce filing. In Cuoco's papers, she claims they separated on Sept. 3.
