Dianna Agron, who helped stir controversy earlier this year by appearing in racy magazine photos with her "Glee" co-stars, is romanced by an alien in the new sci-fi thriller "I Am Number Four".

The movie tells of a group of human-looking beings that hide on Earth from an evil species that destroyed their planet and seeks to hunt them down. Agron plays a Midwestern girl who falls in love with one of the persecuted aliens, who is disguised as a high school student and is played by British actor Alex Pettyfer.

Agron, 24, and Pettyfer, 20, were in August spotted holding hands and playing basketball, MTV News had reported, raising speculation the two are dating. In November, they were photographed leaving a London club together. They have not commented.

Agron plays cheerleader and glee club member Quinn on "Glee", FOX's hit musical sitcom. She and co-stars Lea Michele and Cory Monteith appeared in a racy GQ photo spread and cover earlier this year, which the Parents Television Council said was "near pornographic" and bordered on "pedophilia". Agron said at the time she was sorry if people were offended by it.

"I am Number Four" marks one of Agron's only starring film roles. Before "Glee", which began in 2009, the actress had smaller roles in films such as "The Romantics" with Katie Holmes and had parts in television shows such as "Heroes" and "Numb3rs". She can also be seen in the new Cher and Christina Aguilera musical movie "Burlesque", which is currently in theaters.

Check out the trailer for "I Am Number Four", which is set for release on Feb. 18, 2011.
