Friends fans will recall that in the sitcom's fourth and fifth seasons, Phoebe Buffay was a surrogate for her younger brother, Frank Jr. and his wife Alice.
The friend has her brother's babies, triplets who are named Leslie, Frank Jr. Jr. and Chandler.
The triplets were played by multiple actors throughout the duration of the show, but Alexandria, Paul, Justin and Cole Cimoch portrayed them in the season six episode, The One With Joey's Porsche.
Alexandria has recently gone viral on TikTok after revealing her former role on the show in a video, posting a clip showing baby her on Chandler's lap, while Phoebe is babysitting.
She captioned the post: "Yes... I was on Friends."

The clip garnered more than two million views and many couldn't help but notice how much the university student looks like Lisa Kudrow, who portrayed her aunt on the show.
"OMG you look like Phoebe," proclaimed one user.
Another said: "Now you kinda look like Phoebe."
"This is so iconic, and you even kinda look like Lisa Kudrow now," proclaimed a third.

Others were more excited about the fact that Alexandria was held by Matthew Perry during the episode.
"You were held by CHANDLER BING," exclaimed a different person.
Someone else commented: "Matthew Perry held you. You are my goddess."
Alexandria, who is currently studying at the University of Wisconsin, also shared a few behind-the-scenes secrets from the show.
She revealed that the four of them were used in the episode as triplets, with one of her brothers having to play a baby girl to fit in with the storyline.
The Cimoch siblings only portrayed the triplets as babies - with Leslie, Chandler and Frank Jr. Jr. being recast when they got older in later seasons.
However, Alexandria hasn't completely given up on acting since then and recently appeared in a production of the musical Hair.
