The prefect prelude to their summer tour together!
Check out Nicki Minaj's performance of Super Bass at last night's 2011 Billboard Music Awards, which then segued into her remix of 'Till The World Ends, with an appearance from Miz Britney Spears herself (above)!
We wish our Brit could have given a little more energy during this one, but all in all, she looked great and Her Minajesty KILLED IT as per usual, so we can't complain!
Hopefully these two will continue to perform together during the Femme Fatale tour!
Have fun, ladies!
