Are Olivia Wilde and Ryan Gosling Dating?

She separated from her Italian prince husband early last month after 8 years of marriage and now Olivia Wilde, 26, is rumored to be dating Hollywood hottie, Ryan Gosling, 32.

Not only were the "Tron: Legacy" and "Blue Valentine" stars caught on tape at a Cincinnati aquarium last week by a fellow fish fan, but, according to eonline.com's resident gossip king, Ted Cassablanca, they were also seen canoodling up a storm back in January at an industry shindig in Beverly Hills following the Golden Globe awards.

"They talked for a while inside the show during commercial breaks. Then when Olivia saw [Ryan] at the afterparty she went right up to his table," a source told Cassablanca. "They were talking and laughing together for a long time. They looked cute!" (She, of course, looks as beautiful as ever with her new dark hairstyle.)

Gosling, who's been linked with many famous females -- from Sandra Bullock to Rachel McAdams -- is currently shooting "The Ides of March" in Ohio with George Clooney and Evan Rachael Wood. Wonder if Olivia will head back for another day of tourist attractions - this time a trip to the zoo perhaps -- after all, the Cincinnati Zoo is one of the best in the country.
