Kobe Bryant & Carmelo Anthony -- DITCHED BY WIVES ... It's Girls' Night Out!

No men? No problem ... at least for Vanessa Bryant and La La Anthony ... who took some time away from their famous husbands last night for a basketball wives dinner date in L.A. ... and TMZ has the footage.

The two hit up Madeo in West Hollywood -- without Kobe Bryant or Carmelo Anthony -- and after the meal, they posed up for photogs who snapped away like crazy.

So, are there actual NBA implications from the dinner date? Well, Carmelo becomes a free agent after this upcoming season ... and the Bryants could be trying to woo Carmelo away from NY and sign on with the Lakers.
