The pair, who announced their engagement in December, are looking forward to tying the knot in front of friends and family, reported Us magazine.
Longoria, 41, and Baston, 47, who first stepped out as a couple in November 2013, got engaged in Dubai, where the divorced father of three proposed to the actress with a massive ruby engagement ring.
This will be the third marriage for Longoria, who was previously married to actor Tyler Christopher and NBA star Tony Parker.
