Jennifer Aniston and Justin Theroux have apparently reunited putting rumours there is trouble in the romance to bed.

The 43-year-old actress had enjoyed a European vacation with her hunky lover earlier this summer but they have been apart over the past few weeks.

While Jennifer is filming We're the Millers alongside Jason Sudeikis in Wilmington, N.C., Justin has been travelling between New York and Los Angeles.

But with his 41st birthday this Friday Justin has apparently swung into town to celebrate with his lady love.

Jennifer plays a stripper in the movie which sees her pair up once again with her Horrible Bosses co-star.

Meanwhile, the Wanderlust actor was seen late last month spending time with Jennifer's friend Courteney Cox, her daughter Coco, Laura Dern and her son Ellery and daughter Jaya.

"Everyone was talking and laughing and having a great time," a source told People. "Everyone seemed very close and all good friends."

Jennifer's rep was forced to hit back at claims this week that the pair had split saying all was well in the couple's 15-month relationship.
