Eva Mendes’ Engaging Smile

Mendes engaging smile ne short

The ring’s the thing for bombshell Eva Mendes and “Crazy, Stupid, Love” beau Ryan Gosling, as the actress is flashing an engagement-worthy sparkler all over town!

Eva’s monster rock looks to be an emerald set in a platinum band, and big enough to make anyone green with envy, The National ENQUIRER has learned.

Our spies first caught 41-year-old Eva modeling the bauble on June 21. Since then, the “2 Fast 2 Furious” star’s ring has been spotted numerous times, though she wears it on her right hand and not the telltale left.

Eva and Ryan, 34, are celebrating daughter Esmeralda’s birthday this fall.

What better time to make it all official in the eyes of the law?
