Eva Longoria is slamming rumors she and Lakers forward Matt Barnes are an item -- saying, "Once again, press gets it wrong. Matt barnes and I are not dating!"

Eva took to her WhoSay page to silence the rumors -- adding, "We are doing a charity event together for Padres and Athletes versus Cancer ... why is the truth never the headline?"

Rumors swirled when the two were spotted together at a dinner in New York last week looking "very flirty" -- according to the New York Post's Page Six.

Eva's rep also formally dismissed the rumors -- insisting the two were "just friends."
