Scarlett Johansson is single again after splitting from her boyfriend of ten months, Nate Naylor. The 27-year-old actress has dumped the advertising executive just days after she was spotted ”completely flirting” with one of Lindsay Lohan’s close friends. ”They never officially lived together, but Nate has moved all of his stuff out and back into his apartment. The relationship is over. It has not been amicable,” Contactmusic quoted a source as telling the Daily Mail. The ‘Hitchcock’ star, who was previously married to Ryan Reynolds, began dating 38-year-old Nate last January after meeting him in New York. The split follows several reports suggesting the actress was seen flirting with multiple men, including her ex-boyfriend Jared Leto recently.
