Eva Longoria is now officially single. She split from boyfriend Ernesto Arguello this week after dating for roughly 4 months. The two met while Longoria was producing her dating show "Ready for Love." Ernesto was a bachelor on the program, but after the show went off the air, Eva decided to take Ernesto for herself. Eva and Ernesto were spotted canoodling in Spain as recently as two weeks ago (above), but once they got back to L.A., we're told they decided their busy lifestyles just didn't mesh.
