Eva Longoria yellow dress heels mario lopez extra the grove

Eva Longoria and Mario Lopez make such a cute couple, even if the two hotties are just close friends.

While Mario took care of his hosting duties for Extra at The Grove, his BFF Eva stopped by for a few good laughs and to show off her adorable yellow dress.

The sexy Desperate Housewives star has been dating beau Eduardo Cruz for the past nine months, but as we reported yesterday, Eva is not engaged ... yet. We have a feeling Mario knows Eva's relationship secrets.

We'll be watching to see if Eduardo ends up putting a ring on it!
