The Modern Family star, 39, has been dating Nick Loeb since meeting him at a Golden Globes party in 2010, but they are said to have parted ways last weekend (05-06May12) after a series of arguments.
Vergara then attended New York's annual Costume Institute Gala on Monday (07May12) solo.
A source tells New York Post gossip column Page Six, "Sofia was confiding in friends at the ball that she and Nick have split. They have been fighting a lot recently and have been on the brink of splitting many times. It is not yet clear if they are over for good, but they are done as a couple for now."
Vergara, who has a teenage son called Manolo from a previous relationship, recently revealed Loeb wanted to start a family with her, but she was considering freezing her eggs as she didn't feel ready to have another child.
She said, "We have a very happy relationship... Nick wants babies. Imagine me, again with a baby, when Manolo is 20! I guess eventually I'll do it - for love."
Set during the Spanish Civil War of the 1940s—a favorite area of exploration for writer-director Guillermo del Toro—the story follows dreamy 11-year-old Ofelia (Ivana Baquero) as she’s uprooted and relocated to a remote military outpost when her sickly mother (Ariadna Gil) marries the wantonly cruel camp commander Captain Vidal (Sergei Lopez). With the compassionate but secretive housekeeper Mercedes (Maribel Verdu) as the closest thing to a friend she has in the oppressive environment Ofelia escapes into a richly textured fantasy world. She follows a dragonfly she believes is a fairy into a landscaped but neglected garden maze she recasts as the lair of the goatish godling Pan (Doug Jones). He tells her she’s the last heir to a magical otherworldly kingdom and charges her with several tasks to help her reclaim her birthright. As her personal world grows more and more grim—the impending birth of her half-brother threatens her mother’s health her step-father grows colder and colder in his bid to crush the resistance and Mercedes’ hidden agenda places her in jeopardy as well—Ofelia soon finds herself tangling with hideous monsters both imagined and all too real often having difficulty distinguishing which is the more dangerous. The astonishingly real performance of the amazing young Spanish actress Baquero as Ofelia anchors the film firmly in both its real world and fantasy environments as only the convincing imagination of a child could. Lopez is an equally compelling discovery as the callous Vidal pitiless vicious and malevolent while still remaining believably human throughout. He’s unblinking in his depiction of a thoroughly vile and cruel man but avoids any aspect of cartoonish evil. And Verdu (Y Tu Mama Tambien) as Mercedes is a wonder as well with her remarkably expressive face unlimited by the film’s Spanish language barriers. Kudos too to Doug Jones a whisper-thin actor who specializes in “creature” roles (he’s played Abe Sapien in del Toro’s Hellboy and will be the Silver Surfer in the Fantastic Four sequel) who somehow magically delivers fully-formed performances as both the faun Pan and the freakish Pale Man through layers and layers of latex. Pan's Labyrinth is unquestionably Guillermo del Toro’s finest film work to date as pure an artistic vision as is likely to be committed to celluloid. He wisely worked outside the Hollywood system in his native Spain to bring his dark tale to life. The story exists in that shadowy netherworld between childhood and adulthood innocence and awareness of the world’s more sinister nature and its characters and themes are explored in ways that no mainstream film would ever allow. On the surface the trappings are Tim Burton-esque but the dark corners Pan's Labyrinth peers into are grim and gloomy indeed; del Toro is never afraid to delve into the murkiest of directions that to audiences used to more conventional movies are heart-wrenching even gut-churning but ultimately emotionally honest and in unexpected ways as immensely satisfying as they are haunting. The film is the announcement of the complete arrival of a major filmmaker and we can only hope that the qualities del Toro brings to this work do not get lost in the maze of Hollywood for future films.
