Jennifer Aniston's breakup with Justin Theroux seemed to have really happened after a new report came out that "The Leftovers" actor doesn't really like her frienship with Chelsea Handler.

On the March 24 report of Star magazine, a source told the publication that Justin Theroux thinks Chelsea Handler is "rude and obnoxious."

"He feels she lures Jen to parties and encourages her to act like she's single," the source said.

Breakup rumors between Jennifer Aniston and Justin Theroux have hounded the couple after they weren't seen together for the past few months. While they were apart, he stayed in his NYC apartment while she stayed in her multi-million dollar home in Beverly Hills.

The breakup rumors hit a new high when Justin Theroux failed to attend Jennifer Aniston's 45th birthday celebration as he was busy filming scenes for his TV series with HBO in New York.

Chelsea Handler is a standup comic and host of her own self-titled show. According to MailOnline, she is known to be a "heavy drinker" and a party lover.

The website added that both Jennifer Aniston and Chelsea Handler were spotted drinking cocktails on different ocassions in SoHo House, Sunset Tower and Chateau Marmont.

More than the parties, however, Justin Theroux reportedly believed that Chelsea Handler is "user friendly" and is just using Jennifer Aniston to propel herself to stardom.

"Jen is basically Hollywood royalty and Chelsea uses her to increase her own fame," the source told Star.

And Chelsea knows only too well that Justin Theroux doesn't like her but she just doesn't care. "Chelsea gets off on stirring the pot. She loves getting people riled up," the source added.

The lovely pair, however, seems to have gotten past the breakup rumors as Justin Theroux and Jennifer Aniston attended the pre-Oscars party in Los Angeles on March 2 and were inseparable according to witnesses, In Touch said.
