The boy band headed out this morning (21 January) to launch their Union J dolls in the capital and made sure all eyes were on them by posing inside large pink boxes, similar to the ones their dolls are sold in.
Josh Cuthbert, JJ Hamblett, Jaymi Hensley and George Shelley each dressed up in exactly the same clothes as their toy mini-mes, donning jeans, trainers and various jackets.
The resemblance is uncanny!
Curly-haired George looked like he was having a particularly great time with his look-a-like doll, which is even sporting his signature hairstyle.
He tweeted his amazement about the toys earlier today, saying: "They look sooo realistic! Pouts and Curls alike!... I found my twin!"
The foursome found fame on The X Factor in 2012 and finished in a respectable fourth place.
They have since been busy building an impressive fan base, working on new music and even penning their first book called Union J Our Story.
Band member JJ Hamblett has been particularly rushed off his feet lately, as he and girlfriend Caterina Lopez welcomed their first child into the world in November.
Caterina gave birth to the couple's son Princeton in November and JJ can't stop gushing about how proud he is to be a dad.
We wonder if he gave Princeton a set of Union J dolls to play with?!
