Jennifer Aniston Engagement Ring Features Large Diamond (PHOTO)

Jennifer Aniston recently debuted her engagement ring during an outing in New Mexico where she was accompanied by her fiancé Justin Theroux.

The former 43-year-old former "Friends" star was photographed caressing Theroux's face in Santa Fe on Saturday, revealing what appeared to be a large oval-shaped diamond ring. Theroux was reportedly visiting Aniston, who is currently filming "We Are the Millers" in the area, according to

"Everyone is really excited for them," a source previously told the publication. "It's amazing to see how happy Justin makes Jen, and everyone was always hoping that he would propose."

Aniston, who accepted 41-year-old Theroux's proposal in August, is said to be thrilled with her new sparkler and the actress has reportedly been boasting about it to friends.

"Just after Jen got engaged, she called all her friends and told them about it," an insider reportedly told Life & Style magazine. "She was so happy and said she loves the ring. I think she was overwhelmed and overjoyed by the size and beauty of it!"

Theroux proposed to his unsuspecting girlfriend of one year at the Blue Hill restaurant in Greenwich Village, New York City. Despite recent reports that the pair had split, the couple is very much still together and Theroux's representative previously confirmed their engagement.

"Justin Theroux had an amazing birthday Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage," Theroux's representative Ina Treciokas said in a statement.

It was recently revealed that Theroux has convinced Aniston to invite her mother, Nancy Dow, to their wedding ceremony following their 12-year estrangement. Years ago, Dow reportedly did tell-all press interviews despite Aniston's requests for privacy, which damaged their relationship.

"Nancy and Jennifer have had their ups and downs, but they're going to let bygones be bygones and she will be invited to her daughter's wedding ceremony," a family insider reportedly told

"She was told of the invitation by her son, John, which she was obviously delighted with. Sadly, the initial fallout between Nancy and Jennifer in 1999 meant that she wasn't on the guest list for the 2000 wedding to Brad Pitt- something that always haunted her," the source went on.
