Looks like two more of Hollywood's hottest bachelors may be off the market -- and their latest co-stars are to blame!

Ryan Gosling and Jake Gyllenhaal were both spotted this week showing some PDA with the female leads from their latest movies.

Gosling was seen holding hands, kissing and going on rides at Disneyland with "The Place Beyond the Pines" co-star Eva Mendes over the weekend. Dating his cast mates is nothing new to Ryan, who previously dated Rachel McAdams from "The Notebook" and his "Murder by Numbers" co-star Sandra Bullock.

While Ryan and Eva look like the real deal, Jake's situation isn't as cut and dry.

Gyllenhaal was seen with his arm around "End of Watch" co-star Anna Kendrick outside a Subway on the way to Nevada, where they're likely filming their cop flick.

The two could merely be friends, since Jake was also seen this week with "Parks and Recreation" star Rashida Jones.
