The Friends star was attending the Screen Actors Guild Awards where she was spotted wearing a huge diamond on her ring finger.
Aniston was nominated for Outstanding Performance by a Female Actor in a Drama Series for her series, The Morning Show.
However, the 55-year-old lost out to The Crown’s Elizabeth Debicki.
The actress dazzled at the awards wearing a silver floor-length dress, but it was the sparkles coming from her hand that had drawn the attention of fans.
Although she hasn’t been romantically linked to anyone in recent years, Jennifer appeared at the Los Angeles ceremony sporting a huge diamond rock on her ring finger.
In 2022, the Just Go with It star said: “I’d love a relationship.
“There are moments I want to just crawl up in a ball and say, ‘I need support.’
“It would be wonderful to come home and fall into somebody’s arms and say, ‘That was a tough day.’”
