People shocked by transformation of Outnumbered child stars

For years they were the child stars of hit BBC sitcom Outnumbered.

But now youngsters Ramona Marquez, Daniel Roche and Tyger Drew-Honey have all grown up - and many people can't believe the transformation.

This picture, widely circulated on social media and believed to have originated from Ramona's private Instagram account, shows the actors reunited.

The trio starred alongside Hugh Dennis and Claire Skinner in the show, which aired from 2007 to 2014.

Ramona, who played Karen, was just six when the series began, Daniel was seven when he took up the role of Ben and Tyger, who played Jake, was aged 11.

They are now 15, 16 and 20 respectively and look a lot different.

Many fans took to Twitter to express their disbelief at the transformation.

Aimee Louise Brown wrote: "I've never been so unprepared for a picture in my entire life...why did Ben turn into a tree"

The Sun newspaper reported that Outnumbered is due to return for a one-off special this year, which could explain the reunion.
