Couple Jennifer Aniston and Justin Theroux shot down the breakup rumors as they reunited in L.A. after spending weeks apart from each other.

Justin Theroux was snapped going to the gym in West Hollywood as he tries to maintain his buff physique. Afterwards, he drove his motorbike to Jennifer Aniston's house on Monday, E! reported.

Jennifer Aniston and her  fiancé Justin Theroux have been the subjects of breakup rumors long before she spent her 45^th birthday alone in Los Angeles while he stayed in New York filming his new HBO series "The Leftovers."

But the news website sought out a source who confirmed that the lovely pair is still very much together.

The former "Friends" star Jennifer Aniston has also been rumored to be pregnant although recent photos of Justin Theroux's fiancee suggest no baby belly.

Jennifer Aniston and Justin Theroux were earlier reported to have been "barely communicating" as the wedding plans haven't advanced at all this year, according to the report by MailOnline.

Among the couple's most discussed issues is Justin Theroux's "passivity on the wedding and there have been more than a few arguments on the subject lately," the insided added.

 "She feels like he's broken his pledge to be more proactive when it comes to wedding planning- he consistently won't finalize agreement for a date and 18 months after they got engaged, she just feels he's been doing less than ever," the source told MailOnline.

A breakup between Jennifer Aniston and Justin Theroux is just a matter of time, the Star reported earlier, as the hunky actor already dumped the actress when couple's therapy didn't go too well.

"They were doing couples therapy twice a week before the Cabo trip, but since then Justin's refused to go anymore...He felt like they were just going around in circles with no end result, so he decided it was a waste of time," the source told Star.
