Alexis Jordan's enjoying an incredible 2010.
The America's Got Talent star has got her first single out, "Happiness". It reached number one on US dance charts and the 18 year old says "U never thought it was going to be so massive it seems crazy. I love watching people dance to it."
Alexis is signed to Sony Music through Jay-Z's record label StarRoc.
She popped into see Rich and Kat and they wasted no time showing her their dance moves and asking her about sampling Deadmau5.
They also wanted to know if there were any surprise collaborations up her sleeve, perhaps fellow 'Got Talent Star' Susan Boyle?!!
