Mauricio Umansky‘s trying to have a good time outside the courtroom … hanging with a new friend while a legal battle rages.

The ‘Real Housewives’ star was spotted leaving the Sunset Towers Hotel Friday night with Destiny Herzog — a star on season 6 of “Love Island USA.”

The two laughed and smiled together while driving away from the establishment … which boasts the celebrity hotspot Tower Bar & Restaurant.

Herzog’s clearly got Umansky’s spirits up … and he needs it — because according to court documents, Mauricio’s father’s longtime girlfriend, Simin Tabibnia, fired back at the lawsuit filed by Mauricio’s family. 

Remember … Mauricio’s sister accused Simin of financial elder abuse of her and Mauricio’s father, Eduardo — alleging Simin spent more than $400K of Eduardo’s money on various personal items.

Simin’s response said, “The alleged transfers occurred during an 18-year intimate romantic relationship between Simin and [Eduardo]” adding “payments were voluntarily made by [Eduardo].” 

Eduardo got a restraining order against Simin last year. Simon attempted to get her own order of protection, but was denied.
