Jennifer Aniston is one of a few celebrities who can be the best road trip buddies, according to __. When it comes to her lovelife, however, the former Friends darling is described to be rather "insecure."

A recent survey of movie fans showed the former Rachel Green would provide a great company in road trips, according to 13.5 per cent of the survey respondents. Aniston is the top choice among the fans.

Meanwhile, the British edition of Grazia reportedly spoke to one of Aniston's friends, who said the former wife of Brad Pitt is ready to get married again.

"Jen is, unfortunately, feeling quite insecure in the relationship at the moment, so the next few weeks are crucial. She seems so nervous she can hardly breathe," a source told the British edition of Grazia.

The couple has been recently photographed together in their romantic getaway in Paris. It is said the holiday meant to bring the spark back to their reportedly troubled relationship.

"The plan for Paris was to focus on romance and one-on-one time away from LA... They are both really hopeful it will get things back on track," Grazia's source added.

For his part, Aniston's beau, Justin Theroux, has denied all reports about trouble in their relationship with a statement in the U.S. television show Extra.

"I always go to bed thinking I'm the luckiest guy in the world," Theroux said.

Aniston and Theroux have been together for a year. They met while filming Wanderlust. The two had reportedly resorted to couple's therapy to resolve their issues.

Reacting on the survey for movie fans, Sky Movies scheduling manager Jade Tan said, "(C)omedy is the best policy for a roadtrip partner."

Simon Pegg follows in second with 10 per cent of the votes, and Jim Carrey ranked third with 8.5 per cent votes.
