Former Friends star Courteney Cox shared a throwback picture of the revered sitcom’s cast before the show aired and made them household names.

Cox, who played Monica throughout Friends’ 10-year run beginning in 1994, posted the image to Instagram.

The snap features a youthful cast, including Cox, Matt Le Blanc (Joey), Matthew Perry (Chandler), David Schwimmer (Ross), Lisa Kudrow, (Phoebe) and Jennifer Aniston (Rachel) on a flight to Las Vegas.

Cox, 54, captioned it: “The one where the six of us went to Vegas and no one knew we were F.R.I.E.N.D.S yet #tbt #beforeitaired #lovetheseguys.”

Friends aired in the US on September 22 1994 and became one of the most successful TV shows ever, catapulting its cast to global stardom.

It originally centred on the cast members as twenty-somethings trying to navigate life in New York City.

Its final episode, which aired on May 6 2004, was watched by 52.5 million viewers in the US.

Despite frequent rumours and the demands of fans, so far the cast has resisted temptations to reunite for a follow-up.
