Katie Cassidy and Jerry Ferrara have sparked speculation they are a couple after they were spotted looking close in Vancouver, Canada on Sunday.

The Entourage star, 32, and actress Cassidy were photographed hand-in-hand as they enjoyed a stroll around the city together.

Ferrara, who has previously dated actress Jamie-Lynn Sigler, and 25-year-old Cassidy also cuddled during the walk and dined at The Mill restaurant on their day out, according to website JustJared.com.

Both stars took to their Twitter.com pages on Monday and posted cryptic messages - Ferrera declared, "Thanks Vancouver. It's been real", while Cassidy wrote, "We miss you goose... @jerrycferrara."
