(Cover) - EN Showbiz - Olivia Wilde thinks Daniel Craig is the "most beautiful man on earth".

The American actress is starring in the upcoming science fiction thriller Cowboys & Aliens opposite the hunky British star, and says she was thrilled to be working with the actor.

The 27-year-old beauty insists her time shooting the Jon Favreau-directed western movie was made all the more exciting because she had Daniel to gaze at.

"He is the most beautiful man on earth. He really is," she gushed. "I got enough of Daniel to keep me going for a year."

Olivia, who plays cowgirl Ella in the movie, appreciated Daniel's western wardrobe. The stunning star has recalled the actor wearing "tight" chaps because of deliberate direction from female execs on the movie.

"They kept making them tighter," she laughed in an interview with E! Online. "You could tell we had female executives because he kept getting tighter pants and he would have random shirtless scenes. We were like, 'Yes, finally the ladies are in charge!'"

Meanwhile, Olivia has confessed to dating a celebrity, just not of the human kind. The former model, who has previously being linked to Justin Timberlake and Bradley Cooper, says she's the only male she's getting cosy with right now is her dog.

"My boyfriend is Paco," she confessed."He was actually the Old Navy dog in 2005, so he gets recognised on the street. So I am dating a celebrityhe's just a dog." (C) Cover Media
