Jennifer Aniston has no plans to get married soon.

The 'Horrible Bosses' star, who got engaged to Justin Theroux in August 2012, has allegedly put their wedding plans on hold as she is feeling "extremely insecure" about their future together.

A source told gossip website RadarOnline.com that the actress' decision to celebrate her 45th birthday earlier this month with friends, including Courteney Cox, in Los Angeles instead of flying to see her fiancé, who is working in New York, is "indicative of the status" of their relationship.

The insider said: "Justin asked Jen to come to New York City but she declined, citing the cold weather. She wanted to be in sunny Southern California with her friends.

"It's absolutely indicative of the status of Jen and Justin's relationship. There is absolutely no wedding talk or planning going on. Publicly the couple is saying it's because they are just too busy with work, but if they wanted to get married, it would happen."

The source added: "The relationship is definitely at an impasse...either it's going to fizzle out, which seems likely, or they get married. Jen is extremely insecure and very needy.... Justin is the opposite, very laid back and low maintenance."

Jennifer, who was spotted wearing her engagement ring and a necklace with the letter 'T' for Theroux at an event last week, previously admitted she was in no rush to get married.

Last summer, she said: "We just want to do it when it's perfect, and we're not rushed, and no one is rushing from a job or rushing to a job."
