The pair have become close while shooting the `Total Recall` remake and the American actress - who split from Justin Timberlake in March - is believed to be smitten with the hunky actor. A source told MailOnline: "Jessica loves Colin`s accent and personality. "She`s completely over Justin, she`s having fun being single and thinks Colin is a blast. They`ve been hanging out between takes and Colin`s suggested they go out after work." Jessica and singer-and-actor Justin split because there was no longer any "romance" in their relationship according to pals. A source said: "Justin truly thought he`d found the one in Jessica and she felt the same. But the relationship just didn`t seem to go anywhere. "They`ve both been working incredibly hard and will remain friendly - but there`s no more romance." Colin is not the first co-star Jessica, 29, has been linked with. She was recently spotted on a romantic bike ride with Gerard Butler and enjoying a romantic dinner with him at a Japanese restaurant in Louisiana, during which they sat side-by-side. Jessica was previously linked to Edward Norton after they starred in `The Illusionist`.
