The Wanted singer Max George meanwhile also sent a message about the group, adding:

"Good luck to @thesaturdays tonight on their show in America ... 5 lovely girlies! X."

The 'What About You' stars tweeted that episode two of the series is set to be shown in North America tonight (January 21), revealing:

"Team Sats North America! We are spoiling YOU! Episode 2 of #ChasingTheSats airs tomorrow (Monday night) at 10pm on E! Tune in and tweet!"
