Nicki's given Britney a unique gift after supporting her on tour.
Nicki Minaj is giving Britney Spears personal one-to-one rap coaching.
A backstage snoop says Britney is a big fan of rapping and has been taking tips from Nicki.
"Brit has done a few raps with Nicki and loves Biggie Smalls and Snoop (Dogg)," a source told the Daily Mirror.
"She is event talking about switching things up to a rap vibe for a future album."
Nicki completed her stint supporting Brit on tour with a final date last night in Canada, and there was much mutual love on Twitter between the two.
"Popped bottles w/the crew. Did my final meet & greet. (Got proposed to twice)," Nicki posted.
"Gave brit flowers and told her she's an icon."
And Brit was quick to follow with some Nicki Minaj appreciation.
