Ross Geller was 26 during Season 1 (1994) of Friends, when he had his son Ben.
In the later seasons of Friends, Cole Sprouse played the role of Ben...
...and Cole will turn 30 next month:
Also on Friends, Ross and Rachel's daughter Emma Geller-Green was born on April 4, 2002 — so she's 20 now!
Just for some context, this means, for example, Olivia Rodrigo (born February 20, 2003) wasn't alive when Emma was born.
And here's what Cali and Noelle Sheldon, the twins who played her, look like now — they'll be 20 this month:
Jackée Harry was 38 when she started playing Tia and Tamera's mother Lisa Landry on Sister, Sister in 1994...
...Tia and Tamera Mowry are now 44.
Moira Kelly was 35 when she started playing Lucas's mom Karen on One Tree Hill in 2003...
...Chad Michael Murray is now 40 — and he even played a father (or, well, father figure/cult leader) on The CW's Riverdale:
Bob Saget was 31, John Stamos was 24 (!!!!), and Dave Coulier was 28 when Full House premiered in 1987:
Naturally, all of the Tanner girls are significantly older now than their father figures were on the show.
But the part that's pretty wild to me is that Blake and Dylan Tuomy-Wilhoit, who played Alex and Nicky, are 31 now, which means they're older than John Stamos and Dave Coulier and the same age that Bob Saget was during Season 1.
Here's what Blake looks like now:
And here's Dylan:
Natasha Richardson was 35 when she played Elizabeth James in The Parent Trap in 1998...
...and Lindsay Lohan just turned 36 this summer:
Tina Fey was 34 and Amy Poehler was 33 when they played Ms. Norbury and Regina's mom in Mean Girls in 2004...
...and all of the Plastics (aka Lindsay Lohan, Rachel McAdams, Lacey Chabert, and Amanda Seyfried) are now old enough to be camcorder-carrying moms themselves:
And here are all the Plastics "reunited" on Zoom in 2020:
Alexis Bledel is now 40, which is the same age that Lauren Graham was when Gilmore Girls ENDED in 2007.
