Nicki Minaj's edition of MAC's recurring, celeb-endorsed Viva Glam lipstick line is the best-selling shade in the long-running range! There is a reason that it's a big deal, and it's not boastful or ego-driven.

Every cent of the selling price of MAC's Viva Glam lipsticks and lip glosses goes to the MAC Viva Glam AIDS Fund, which benefits men, women and children living with the disease.

Minaj's shade is pink, of course, which is her favorite color. She tweeted the good news that the shade she sponsors is tops in sales. She held up a giant tube of the lipstick for effect.

She tweeted: "#1 selling viva glam lipstick of all time... thank u for supporting a good cause. mmmuuuaaahhh!!!!"

It's also a big deal since Lady Gaga also branded Viva Glam, so here's one area where Her Minajesty trumps the Mother Monster.

That said, big ups to Minaj and MAC and their efforts to help those with AIDS via a pretty pale pink lipstick.
