Amanda Seyfried says her dog is the only man in her life.

The 'Mamma Mia!' actress - who has recently been linked to sports entrepreneur Franck Raharinosy and real estate executive Andrew Joblon - insists she dedicates all her time to her pet pooch so has no room in her life for romance.

When asked what she is looking for in a man, Amanda told America's OK! magazine: "Oh, nothing at all right now. My mind is on my dog. He's my best friend. I love him. I think of him and only him. I don't like to be out late because I just want to go home to my dog."

Amanda - who recently split from Hollywood hunk Ryan Phillippe - also insists she is just friends with Franck, despite them recently attending the US Open tennis tournament in New York.

She said: "Oh I'm friends with him. He's a good, smart guy. And he's fun. He loves tennis, he loves ping-pong. They all do. They're all really into that sport. It's fun."

Amanda - who dated her 'Mamma Mia!' co-star Dominic Cooper for three years - recently admitted she likes to keep men guessing, and thinks "mystery is really sexy".

She said: "I don't think men find me irresistible at all. I've got a filthy side and a romantic side - I like to keep them guessing.

"Mystery is really sexy. Bad guys also tend to be really self-centred and very fearless - I don't know why but that is sexy. It shouldn't be, it's disgusting."
