Jennifer Aniston was 25 years old when she started on Friends , which premiered on September 22, 1994. She then turned 26 during the run of the first season.

Quick Scoop

  • Jennifer Aniston was born on February 11, 1969.
  • The Friends pilot aired in late September 1994, making her 25 at the time.
  • She celebrated her 26th birthday while season 1 was still airing, so during that first year of Friends she was 25–26 years old.

Fun bit of context

  • Her character Rachel Green is written as being in her mid‑20s at the start, so Aniston’s real-life age lined up closely with Rachel’s on-screen age, adding to the show’s relatability.
  • Across the full run of Friends (1994–2004), Aniston went from 25 to 35, growing up on screen alongside many fans who watched the show in real time.
