Are some of you really comparing Brit and Iggy's career?

Seriously, stop.
BOTH of them needs this single to be successful. Brit don't have anything to prove or care about either, but a hit single is what she needs now, especially after the Britney Jean fiasco. She's a big star with a flawless discography, they now are "cleaning" the mess. And Iggy needs this to be successful to keep her around and give her a boost, after Trouble and Reclassified flopping.
Who cares if Iggy is promoting? Isn't that good for the single? Why some of you are complaining? I guess Brit's team is satisfied with Iggy since they give her permission to be a feature AND direct the video. Plus, the producer of the song is the same of 90% of Iggy's songs. So i'm sure they trust on her, Britney too.
I'm sure the song will be amazing but i'm so sick of people complaining about Iggy this, Iggy that... just enjoy the damn song and let's hope for be successful. It will be good for BOTH of them, end of story.
And i don't think they will perform on a TV show or something... probably Iggy will perform with her on Vegas. Hope i'm wrong tho.
