The cute pink tutus may have been dispensed with since their last visit in 2011 when they captured the hearts of millions - but their infectious energy and fun personalities are every bit the same. 

The girls - who are from Essex in the U.K. wore matching mint peplum dresses as they explained to the host they have welcomed new siblings since they last met. 

And Rosie's parents also got married at the start of September, with both of the girls playing bridesmaid.

The schoolgirls have been recruited by Ellen as her red carpet hosts for Sunday's AMA's which sees Nicki Minaj, 32, pitched against Taylor Swift, 25,  for Artist of the Year. 

Sophia Grace shared her delight at being back on the show which picked up on their You Tube success in 2011. 

The youngsters had recorded a version of Nicki's Super Bass four years ago when they were just 8 and 5, which became a viral hit - and has had around 50 million views.
