Rumors surfaced earlier this week that Longoria and the 33-year-old Miami, Fla. engineer were dating after they were reportedly spotted going for a drive together on Sunday in L.A. and ended up at Longoria's home.
"Eva is not dating Ernesto," her rep said in a statement to E! News. "She is friends with all of the guys and matchmakers from the show, but nothing further." The currently single star has previously been romantically linked to Penelope Cruz's younger brother Eduardo and NFL star Mark Sanchez following her 2010 divorce from NBC star Tony Parker.
Meanwhile, the fate of Longoria's new reality dating show, Ready for Love, remains unclear. On April 18, Entertainment Weekly reported that the show had been canceled after airing three episodes. On Monday, however, Longoria retorted via Twitter that it was "just changing days."
