A source close to the pair recently told OK that the Desperate Housewives actress and Cruz are "ready to wed" and hoped to tie the knot in the very near future.
Longoria's rep denied that the star has any plans to walk down the aisle right now, insisting to GossipCop that the marriage rumour is "not true".
The Texas-born Longoria wed her first husband Tyler Christopher in 2002, but they split just two years later.
In July 2007, Longoria and NBA star Tony Parker married in front of family and friends in Paris.
Longoria filed for divorce from Parker in November 2010, citing irreconcilable differences as the cause of the split.
Longoria recently joined comedian George Lopez for the final instalment of his Lopez Tonight talkshow.
