Courteney Cox is reportedly blaming her best friend, Jennifer Aniston, for the failure of her relationship with her former fiancé, Snow Patrol guitarist Johnny McDaid.

Aniston allegedly pressured Cox to follow her footsteps and get married as soon as possible. The former secretly wed actor-writer Justin Theroux in August.

"Johnny resented Jen's meddling... [He] even told Jen to back off," said the National Enquirer, quoting an insider.

"Johnny warned Courteney more than once that Jen was stirring up problems, so now Courteney is kicking herself for letting Jen come between them," the insider added.

The source also claimed that Cox is willing to end her friendship with her former "Friends" castmate if McDaid took her back.

However, a source close to Cox denied the claim and said that the two stars' separation had nothing to do with Aniston, and instead revolved around commitment issues and disagreement over living arrangements. McDaid wanted to live in the UK, while Cox insisted that they reside in Los Angeles.

Cox and McDaid began dating in 2013, and announced their engagement in June 2014. The two separated and ended their 18-month relationship just this month.

Cox was previously married to actor David Arquette for 11 years. The two, who met on the set of the cult horror franchise, "Scream", share a daughter together named Coco. If the marriage between Cox and McDaid pushed through, it would have been the first marriage for McDaid.
