The Daily Mail reports on Sunday that the 46-year-old star did look flawless though in a blue sweater dress that she matched with a pair of knee-high boots for her outing. Still, fans can't help but speculate if her relationship with her fiancé has gone downhill as the pair hasn't been seen together for several months now.

According to Star Magazine's print edition this week (via Celebitchy) the couple is allegedly growing apart while Aniston is trying to salvage what she can. An insider says the actress was spotted having a heart-to-heart lunch with her best friend Courteney Cox in Los Angeles recently, where she opened up about her problems with Theroux.

The source said, "She kept saying that, once again, she'd managed to mess up an important relationship," says an eyewitness. "She was talking very loudly. She said her fiance wasn't trying hard enough to save the relationship and she was so tired of always fighting with him."

The insider added, "Jen and Justin have been falling apart since the start of the year. They lead virtually separate lives. You rarely see them together anymore; it's always work, work, work. It was only a matter of time before things fell apart. They're just not that into each other anymore. It's a sad state."
